My question applies to the half-marathon app. I've noticed that by the end of the app, it trains you to do intervals of 4-minute runs and 1-minute walks. This is exactly what I want to do! However, because I run slowly, I doubt I'll finish a half-marathon in the number intervals the app directs you to do. So, my question is, if I have more distance to complete, how to I get the app to continue some more intervals (before the cool-down period)?
Thanks!
