Stryd and Coros Pod 2 are two pods that track a variety of running metrics, including pace, distance, and cadence.
Both devices are designed in a way that helps runners improve their performance and monitor their progress.
On top of that the devices also provide more accurate pace and distance since normally GPS can have a lag and using a running pod can eliminate that delay.

Coros POD2 can be used only with Coros watches, while Stryd can be used with pretty much all popular brands including Coros or even without watch ( smartphone ).

In the table bellow you can see what are the metrics you can collect with having watch and a watch + pod:

</Table>

As you can see the main difference is Stryd measures running power while coros pod
2 is using effort pace, a new metric invented by Coros which tries to simplify pace
while taking into account many other factors like grade.<br />
The other difference wich I really like is the Stryds ability to detect head-wind and see how much of your energe is wasted to overcome it.

So which device is better for you?<br />
That depends on your watch: if you have a Coros one, Coros Pod 2 is a cheaper option, otherwise, Stryd is much better from a compatibility point of view and can be used even when you change your watch ( or without one ).



I've been using Garmin Fenix 7 together with Google Pixel Watch for over a week,
In this post just want to share the data prodiced by both devices for that period.

As you can see from the charts bellow, there are a few aspects in which the devices align very well, and another in they totaly disagree.

After years of rumours, Pixel Watch is finally here. Let’s see if matches the high expectations.

Firstly, this is a review from sport / runner perspective, and I will focus mainly on that side of the watch and trying to answer most important question for me: can this watch provide me with accurate data and help me train.

## Overview

The watch is pretty small, slick and very minimalistic, it's barely noticeable on my wrist, here are quick specs:

- size: 41mm diameter, 36 grams without band
- display: 1.2 inches, 450x450 pixels AMOLED, protected by gorlila glass 5
- water resistance: 50M / 5ATM
- price:
  - $349 / 379 € / £ 339 for WiFi only
  - $399 / 429 € / £ 379 for WiFi + LTE

<br />

## Sport and Running

Pixel Watch utilizes Fitbit for sport and exercise, it comes with 40 sports modes, like Run, Bike, Swim and a few others like Yoga and Functional training, unfortunately, there is no Triathlon yet.

The data which you can see and track on the watch during a run is quite limited, you have only 1 screen with the option to configure 4 fields with the fallowing options: distance
, elapsed time, heart rate, pace, pace avg, calories burned, steps, elevation, elevation gain and active zone minutes.

If you want to see any other data-field during exercise there is a way to do that, you need to swipe right, and you can see the rest of data in a list manner, but that is kind of difficult to do when you are running.
I personaly would love adding option for multiple configurable screens like Garmin or any other sport watch.

<GridLayout columns={{ xs: "1fr", md: "auto auto" }} 
  rowGap="space040" 
  columnGap="space040"
  justifyContent="start"
  >

<Image
  src="/blog/pixel-watch-review/run-screen-goals.png"
  alt=""
  layout="fixed"
  width="300"
  height="300"
/>
</GridLayout>

There is an option to set a goal, like distance, time or calories but not for interval training or structured workouts, I couldn’t find any other application that supports this functionality.
On top of that external sensors are not supported natively and you have to use an external app, at least in that case there are a few options, but more on that later.

So the watch can collect your data like GPS and HR, but is it accurate, lets's find out:

<br />
## Accuracy

For accuracy testing and comparison I did a few runs with Garmin Fenix 7, a smartphone which support dual-frequency satellite and the Pixel Watch.

### GPS

#### Interval Run

All devices seems to cut corners, but the pixel watch does not look worse than my Garmin and smartphone.

Here the pixel is the closes to the path I actually took, I did not run on the street.

My smartphone is way off, and the Garmin is showing the right path, the Pixel is between and eventily down the road, the Garmin and the Pixel aligned.

And between the buildings the Pixel is again the most accurate one.

### Heart rate

for that comparison I used Garmin Fenix 7 with Polar H9 chest strap.

#### Interval Run

<a href="/blog/pixel-watch-review/HR-run-20-oct.png" target="_blank">
  <img src="/blog/pixel-watch-review/HR-run-20-oct.png" width="100%" alt="" />
</a>

Apart from the very beginning where is kind of normal for optical heart rate sensors to struggle for the first few minutes, the rest of the time it matches the chest strap.
In general, I am pretty happy and even surprised with the accuracy. Obviously there are differences of few beats here and there but that’s totally acceptable, the whole trend is pretty equal with my chest strap.

#### Long steady run

<a href="/blog/pixel-watch-review/HR-run-22-oct.png" target="_blank">
  <img src="/blog/pixel-watch-review/HR-run-22-oct.png" width="100%" alt="" />
</a>

As always if you want to have better HR you need to connect external chest strap, which Pixel Watch does not support out of the box, but on that read next part.

### External sensors:

As I said external sensors are not supported by Fitbit app, but you can use one of the folling apps to achieve that:

- [adidas Running](https://play.google.com/store/apps/details?id=com.runtastic.android): can connect to Heart Rate sensor
- [Sporty Go!](https://play.google.com/store/apps/details?id=org.qooapps.sportygo&hl=en_US&gl=US): can connect to Stryd & Heart Rate sensor however it's not free. In my research I found that is probably the best Wear OS app for running right now, it also provides customisable data screens and can sync with Strava.

If you want to check more details about graphs and maps here are links to comparison data sets:

- [Interval running](https://analyze.dcrainmaker.com/#/dcc/2ae85812-59a6-4fb9-59b2-93027c804e55)
- [Long run](https://analyze.dcrainmaker.com/#/dcc/cbf4f40d-007b-467a-4d22-6d86139cd4a1)

<br />

### Other sport metrics

Here is a list of stuff that I expect from a running / sport watch:

- **VO2max score**: yes, it's called Cardio Fitness and can be found in Fitbit's smartphone app.
- **Training Load and Status**: no available at the moment, probably the best way is to sync your runs with 3rd party platform like TrainingPeaks.
- **Daily readiness**: there is a functionality which tell you how ready you are for your day, but it is part of Fitbit Premium ( Google is giving you 6 months for free)

<br />
## Wellbeing

on the well-being side, the pixel watch provides quite a lot of useful features, mainly via the Fitbit app:

- **Daily readiness score**: uses your Fitbit data to assess whether you're ready to workout or should prioritize recovery, it's a score from 0-99 and takes into an account: sleep, HRV and recent activity.
- **Sleep tracking**: I find Fitbit to have one of the best sleep tracking devices, and this seems to match my other fitbits, the watch will provide you with sleep stages, sleep quality score and sleep time.
- **HRV**: overnight measurements on your HRV, later can be seen in the fitbit app.
- **Resting Heart Rate**: measures your heart rate during rest ( mainly sleep )
- **ECG app**: it requires an extra app, unfortunately, I couldn’t test it since it is not supported in my country

## App ecosystem

Apart from the fitness app, Wear OS is the second-best watch operation system after Apple’s one. There are plenty of apps in Google Play Store.

- Strava - you can use it directly from your wrist without the need for a phone
- Music: Spotify, Youtube Music, Shazam and plenty more apps for music, or just to use the watch as a media controller
- You can send and reply to messages in most of the apps.
- You can make phone calls
- You can use the watch as a camera remote.
- Google Wallet for payments
- Google Home for managing your smart home devices
- Google Maps for navigation in the city and Komoot for trails.
- Google Assistant for speaking to someone when you are bored.
- Huge variety of watch faces and pretty much anything you want.

<br />
## Battery

First of all, this is a smartwatch which runs a full functional operation system, similar to Apple Watch OS, having this kind of OS means you can’t expect the watch to last for longer, here is how the battery works for me:

- During **day** is around 3 to 5% per hour
- During **sleep** is around 2.5-3% per hour, or around 20% per night
- During **exercise** with GPS: 14-18% per hour

So it is exactly the same as google advertise it: **up to 24h**, which means you have to charge it every day.
Charging times are pretty good though, and they are what Google says as well: 30 minutes to 50%; 80 minutes to 100%.

<br />
## Conclusion

The Pixel Watch works well for me, I am very happy with the GPS and HR accuracy. The battery is not great and I need to charge it every day but that is the cost of having a full-featured smartwatch. Wellbeing functions are really good. The only real downside is the lack of a good running app that supports training plans and structured workouts, which honestly can be sorted by some smart developer, and it's just a matter of time.

If you are a very active runner or biker who trains and follow training plans, I would not recommend the watch at this point, for the rest, that is a very decent first smartwatch from Google and probably the best Wear OS watch till now.



Years after its competitors Garmin finally started adding Running Power from the watch (without the need of an accessory ).
Just a few days ago as part of Fenix 7 and Epix alpha release, the long waited functionality was introduced to Garmin watches.

In the past, RP required to have HRM chest strap or Garmin pod but from now that's gone.

So after loaded my Fenix with the latest firmware, I went for a run, here is a comparison between Stryd and Garmin:

<a href="/blog/garmin-vs-stryd-power/power-combined.png" target="_blank">

    alt="Chart with power data"
    width="2214"
    height="374"
    layout="intrinsic"
  />
</a>

You can click on the graph bellow to open in large view or see it as <a target="_blank" href="https://docs.google.com/spreadsheets/d/e/2PACX-1vTCPE8w_87k8Td80w3_gndSPNq8mbnssLZWRD-4o_RqdoO-QyF_QTSoGEodm59ijw/pubchart?oid=575774279&format=interactive">live chart here</a>.

I am pretty happy from what I see, the power produced by the watch is pretty much on spot with Stryd,
there are a few delays here and there but that's normal.

On a few occasions, I deliberately increased the pace very sharply or did sudden stops to check how the watch responds,
and I would say everything was GOOD, with a very little delay of 2-3 seconds.

For example here I just stopped, I am not sure why there is some power from garmin since I did not move.

<Image

  height="401"
/>

Overall I am impressed with the quality at least from that single run.
That does not mean I will stop using my stryd,
it is much more responsive, and accurate, and also encounter the wind
which is handy if live in windy place like I do.



I wrote about [HRV in the past](/en/blog/hrv-for-training-intro) and how I found it an extremely useful metric.
As HRV4Training website put it:

> Heart Rate Variability (HRV) insights to help you quantify stress,<br />
> better balance training and lifestyle,<br />
> and improve performance

In this post, I want to compare HRV data collected between Garmin and [HRV4Training](https://HRV4Training.com), as well as the "**readiness score**" these two sources produce.
The data is for two months period, in which I was training for a marathon, and for that time I use [Garmin Fenix 7](https://www.garmin.com/en-US/p/735611) with an alpha/beta version of the software.

---

## HRV

In this chart, you can see HRV values between Garmin and HRV4Training

- HRV4Training was taken every morning for 1 min.
- Garmin was measured during the night.

<iframe

></iframe>

Some additional background:

- On 11 Sept I did a half marathon, in very hard conditions - hot and humid weather.
- Between 14-17 Sept I got a stomach virus so I was feeling pretty bad for 3-4 days.
- On 26 Sept I did a full marathon pretty much all out.

You can see when I was sick and after the races my HRV was pretty low.
In my opinion, trendings are very similar, especially in the last 3 weeks around the races and sickness.

---

## Readiness

Since HRV is mainly about how stressed you are and how hard you should train I've decided to compare also training readiness functionalities.

- HRV4Training is giving you 3 states: Proceed as planned, Limit intensity and Take it easy, I marked these as 3,2,1 points accordingly.
- Garmin Training Readiness is a bit more complex and includes more things than just HRV status, like sleep and time since the last training. Training Readiness here is a value between 1 and 100, to normalize the data 1-24 is 1, 25-49 is 2, and 50-100 is 3.

></iframe>

## Wrapup

Even though I have a Garmin device with HRV capabilities I still find HRV4Training useful, since it has **questionnaire** so in that way you not only can see the HRV value but also has context around it.
And I believe having a context is very important.

On top of that HRV4Training costs only 10 euros ( or less ) compared to high-end Garmin devices, which means you can buy a cheaper device and still enjoy that functionality.



In 2022 as part of its new watch lineup, Garmin also added a set of a few software features with the aim of maximising our training.
Here my list of features which I use almost daily:

---

## Training Readiness

<Image
  src="/blog/garmin-new-software-features-2022/training-readiness-watch.webp"
  alt="Daily suggestions"
  layout="fixed"
  width="350"
  height="425"
/>

As the name suggest, the goal of this feature is to assess how ready you are for training.
Basically it gives you a score from 1 to 100 and a feedback message like **"ready for the day"**.

In order to calculate your readiness for the day it takes into an account few other metrics and combine them into single score:

- **Sleep Score**: how well you slept last night.
- **Sleep History**: how was your sleep over last 7 days.
- **Recovery Time**: how recovered you are after your last workout.
- **HRV Status**: More on that later.
- **Stress History**: How is your stress level in the past 7 days.
- **Acute Training Load**: is a weighted sum of your recent exercise load scores including exercise duration and intensity.

## HRV status

<Image
  src="/blog/garmin-new-software-features-2022/hrv-status-watch.webp"
  alt="Daily suggestions  on the watch"
  layout="fixed"
  width="350"
  height="425"
/>

HRV (Heart Rate Variability ) is the variation in the time interval between two heartbeats.
Apparently, when you are stressed then your heart beats in sync way compared to when you are less stressed.

So the idea of **HRV status** is to provide you with another recovery metric.
Garmin measures your HRV over night and you have your result in the morning.
In order to create your HRV status the watch needs 19 days of over night data collecting and after that creates your baseline.

---

## Daily suggestions

<Image
  src="/blog/garmin-new-software-features-2022/daily-suggestions-watch.webp"
  alt="Daily suggestions on the watch"
  layout="fixed"
  width="350"
  height="425"
/>

As I said most of the new features aim to improve your training,
and now **Daily Suggested Workout** will provide you with a workouts specific for your race.
For example, if you set a race event in your calendar,
the suggested workouts will be according to that event,
and your watch will even create training phases like **build, peak, taper and rocovery**.
Just like real training plan but in a more flexible one.

<GridLayout
  columns={{ xs: "1fr", md: "auto auto" }}
  rowGap="space040"

  alt="Race Calendar on the watch"
  layout="fixed"
  width="350"

**Race calendar widget** is a small widget which shows you information about your next race:

- Time and Date of the Race
- Prediction Time
- Forecast temperature
- Elevation profile
- Course map

<GridLayout columns={{ xs: "1fr", md: "auto auto" }}

  src="/blog/garmin-new-software-features-2022/morning-report.webp"
  alt="Morning report"
  layout="fixed"
  width="350"
  height="425"

When your watch detects you are awake, your daily **Morning Report** popsup on the screen and shows you everything you need to know about the day like:

- Training Readines
- HRV Status
- Workout of the day, including Daily suggestions
- Sleep
- Weather
- Body battery

That's all, thanks for reading.



HRV is used mainly for recovery, but a [recent study](https://aiendurance.com/blog/dfa-alpha-1-thresholds-from-heart-rate-variability) shows that can be used for determining your HR or Powerzoens without the need of doing a ramp test.

Garmin has an algorithm for determining your HR zones but does not have one for Power ( at least at the moment of writing this ). If you use [Stryd platform](https://www.stryd.com) you are fine and can skip this post. For the rest of the runners using one of the newest Garmin watches like Fenix, Epix, Forerunner 255/955 ( it also might work with Fenix 6 when Garmin release the latest update ) you can continue reading the guide:

## Step 1: Turn on HRV recording

To do so go to:

1. Your watch
2. System
3. Data Recording
4. Log HRV
5. Set to **On**

<Image
  src="/blog/using-hrv-and-ai-to-calibrate-zones/loghrv.png"
  layout="fixed"
  width="260"
  height="260"
/>

For better results use a **chest strap** and if you want power zones you will need one from Garmin.

## Step 2: Collect data

Before you are able to calculate your zones, you will need to collect some running data with HRV enabled, I don't know exactly how many runs you need, however, my recommendation is to run for at least a few weeks in different intensities.

## Step 3: Register at [www.AIendurance.com](https://www.AIendurance.com)

AI Endurance is a great platform that uses Artificial Intelligence ( AI ) to create and optimize training plans but that's something for another post.
After you register you will have 2 weeks trial period in which you can import your running data from Garmin or Strava, that might take some time, and after that is done, you can go to your **"Account"** from the main navigation, tick the box for **"Use HRV derived thresholds"** and **"Use running power"** if you want your power or HR zones, after pressing save button you are good to go.

<Image
  src="/blog/using-hrv-and-ai-to-calibrate-zones/aiendurance.png"
  width="1338"
  height="1524"
/>
<br />
<br />

## Step 4: Go to your mobile app

1. Open Garmin Connect on your mobile app and from the menu select Garmin Devices
2. Your watch ( for example Garmin Fenix 7 )
3. User Profile
4. Heart Rate & Power Zones
5. Power / Heart Rate
6. Running
7. Select Based on: Watts
8. Enter your zones in watts from AI Endurance.

<Image
  src="/blog/using-hrv-and-ai-to-calibrate-zones/garmin.jpeg"
  width="720"
  height="1600"
/>

That's all, now you have HR / Power zones.

_The same method
can work for other brands and watches, I will update the post once I know more info
about it._

With that, have a safe run

Finding the balance in anything is always difficult and especially hard in something like training and exercise. For many years I have been struggling to improve my performance and get injured and sick quite often.

About a year ago I started hearing about a thing called HRV, which in simple words is the variation in the time interval between two heartbeats. Apparently, when you are more stressed your heart beats in a more sync way compared to when you are less stressed (I know that might sound counter-intuitive ). Basically, HRV is how your nervous system **responds to stress**, it can not determine the cause of the stress but it's a great indicator of it.

## Measuring HRV

The easiest way to measure HRV is via a smartphone app and its camera.
There are plenty of apps that can do that, I’ve tried a few of them and in my view the best one for running is [HRV4Training](https://www.hrv4training.com/).

## First things in the morning

The way it works is that you need to take a measure after you wake up or at least that’s the recommendation so I do that, and after it, the app is providing with feedback like: you are **good to go** or you need to **take it easy**, I found this really simple and in very useful.

<Image
  src="/blog/hrv-for-training-intro/example1.png"
  alt="hrv for training"
  width="700"
  height="480"
/>

In the past I’ve been sick regularly, like every few weeks, probably pushing too much too often, also combined with other life stress factors I had one of my worst training periods. However, since I start taking HRV measurements I feel much more confident and I bearly been sick since then.

I have to admit that I also started to train much smarter and follow training plans, not just random hard runs here and there but definitely, the feedback from HRV4Training has been crucial for keeping me healthy and improving my performance.

## Ignoring the advice

Yes, sometimes I do have planned some hard sessions and HRV4Training recommends me take it easy, and depending on my schedule I might not take the advice and do the planned session. In some of the cases I’ve been fine, and in others, I’ve had to take a much longer recovery between runs. Even in that cases I still think such apps are helpful.

Take care of yourself that’s the only way we can enjoy our favourite activities.
