Garmin HR Running dynamics vs Stryd

To me it depends. I have a regular Garmin footpod and hrm tri and works fine as I don't really care about the running dynamics and the strap does well enough with the power. It does match stryd but that js irrelevant. Also they both take cr2032 so no charging or battery replacements for a year. 

Get stryd if you dont want or wear a hr strap and don't mind charging it. 

Thanks everybody for the hints. Buckling could be my problem too, I will try figure it out. I have the pod only short time and use it on few runs. But first run in valley on asphalt was about R52, the second run after physiotherapy was 50/50. Yesterday on oval again R51,8 most of the time. Next week I have physiotherapy so I'll see. And yes, I have new shoes with pronation support.

I don’t think that is really an upgrade. The polar straps are interchangeable and better than the fixed Garmin strap. The H10/H9 is the most accurate HRM available. The only reason to use the Garmin one is for cache and send to Garmin watches during swimming. 

The running dynamics metrics are not actionable. Most are just directly proportional to pace. The R/L balance is intriguing but impossible to do anything with. If you have a physical imbalance such as a hamstring injury — it will show up — but you can’t consciously do anything about it. There are other ways to detect that your leg strength is not equal. If you are injured and working with a physio then I’m sure they will be testing you every session, for example. In practice I don’t think there is really anything you can do with the running dynamics to inform your training. Garmin is silent on this also as far as I can tell. It’s nifty but that’s all.

And you know this because?

H10 has memory too, but Garmin can't load that. Even 3-axis accelerometer so it could be able monitor running dynamics too. You can install android app to see that. Or even ECG app that draw your ECG from H10...

I switch from H7 to H10 because I sometimes get too high HR readings while cycling downhill. Probably static electricity caused by wind. But putting gel on electrodes and tighten up seems to solve that. With H10 I never has this problem.

And in my own sample of one non-scientific testing, I find the Polar H9 to have slightly faster tracking response to Garmin HRM3 and HRM-Run (red). However all of those are very good and produce useful and reliable results. 

The new Garmin fully integrated design is a downgrade in my opinion to the earlier snap-on pod design from the HRM3 and original HRM-Run and the contemporary HRM-Dual. The serviceability of the battery in the Polar pod is done without screwdrivers and delicate gaskets that seem to be easily damaged in the Garmin design.

In general the only reason to get the more expensive new Garmin — in my option — is the swim feature with Garmin watches. Especially if you already have running dynamics from Stryd. Or if you work with a coach or physio that can do something useful with the L/R balance or other running dynamics. 

Keep in mind the OP already owns an H10 and a Stryd so the question is if $130 for the new Garmin HRM is a good purchase.
