TR seems good but it looks like the Wahoo app can do the same if I can create the workouts. I could then get a different app for some virtual ride stuff was my thinking...
I tried to get my pre-race warmup onto my Wahoo Elemnt Bolt but came to the conclusion that I'd need a Training Peaks or Today's Plan account to do so. I couldn't find any evidence of a Wahoo workout builder - there was a blog post or something about it but I couldn't find the actual app.
You can’t load TR workouts on a Wahoo. Why not just use the TR app?
