I’m part way into low volume sweetspot base II and am working towards the local cyclocross season. I’m keen to keep riding outside for my workouts for the next month or so but the over under threshold workouts I’m getting recommended in levels 6 & 7 in the coming weeks would be hard to do on local hills. There’s a 15 minute climb about 30 minutes from my house and a 20 minute one 45 minutes away but nothing longer and I’ll need big enough gaps between the intervals to roll back down in between. I was wondering how much difference it would make to my training if I swapped the over unders for other kinds of threshold workout at a similar level:
Mesachie +4 Mount Grant
Keith Rainbow +2
McAdie +4 Rainbow +3 or Deseret
Pinnacle +3 Rainbow +4
Would making those changes affect my training much? Would I be missing out on much by not doing over unders? Am I OK switching into hard start intervals like the Rainbows or should I have done other hard starts first?
