When training outside after a set is done I’d like the next set to begin on lap button. Sometimes I want to do for example 3 vo2 max intervals and then I might be riding thorough a town when the next ones start and it’s not optimal. It’s ok to find 20-30 mins of good roads to get sets in without interruption where I am, but planning an entire workout outside is tough without these urban areas/poor roads etc been ridden thorough. seems an easy and obvious one to me
