    I’ve been a happy 80/20 pace-based running customer for a few years, but have been wondering about running power since my Garmin got updated to measure wrist-based power natively. Have any folks made the switch or perhaps compared it to more established power measurements like stryd? I train for mountain ultras and so was wondering if power is was a way to get a better measurement of effort across hilly terrain because pace drops to 30 minute miles on big climbs. On the other hand, if wrist based power is just a gimmick, I’ll stick to perceived effort on those runs.

    Thanks and happy new year.

    Hi,

    I’ve not done the comparison, but I run over variable terrain (1-200m ascent over 10k) and use power specifically to avoid struggling up hill (potential injury) and coasting down hill when using pace.

    Interestingly Garmin recommends using a separate device for accuracy. https://www.garmin.com/en-US/garmin-technology/running-science/running-dynamics/running-power/

    If it’s free on your watch why not try it? The 8020 folk will give you a power version of your current plan for free.

    Have a look at the new Stryd run profiles – the trail one takes account of switchbacks which might interest you?

    Thanks for sharing your experience. I think “it’s free on your watch why not try it?” is pretty much spot on :).

    My suggestion is to do a simultaneous test then you can see how all your metrics are changing. Eg your Power might not improve but your pace might if your running form improves and you get more efficient.

    RPE is probably the best, but I am rubbish at it – especially keeping in the lower zones. Power helpfully naggs me to keep in zone.
