I just received an email from Runscribe re their new pods which will connect with Garmin watches (Fenix 5 for sure) and measure running power as well as many other things. To say that I already have their existing pods (w/o running power and F5 connectivity) and I am quite happy with it, so I am looking forward for this new ones. Just that I do hope they will work very well with F5 in terms of connectivity (not like Stryd which some users are reporting issues). The new pods will work with Suunto as well.
