After a week with @TrainingPeaks subscribtion, 8020 plan and @watchletic I'm sold! Love to sync my structured workouts directly to the AWU
Can do everything I was looking for. Direct Import/Export with TrainingPeaks, easy creation of more complex runs. Also the feature to get the intermediate results directly to your earphones I dont want to miss. Now only running counts!
I'm always happy to find new apps that can be used to Run with Power - especially when they can be recommended as 'best in class'! I've had the opportunity to test Watchletic over the past few weeks, and have been very impressed - enough to add it as the recommended Apple Watch app when using wrist-based power. And it works with a Stryd footpod too - truly an all-round app (finally!).
I use this app when running and it’s great. I can easily set a variable distance when I want to start my workout. Simply a time saver. Developer listens to feedback and implements features/changes where he can.
Watchletic's core workout features are free. Join Watchletic Club to import scheduled workouts, import FIT files, and unlock advanced workout graphs. Your local price is shown before purchase. Feature availability can vary by platform and watch model.
