Yup i reckon so Mol. I’ve entered a mountain TT (25miles) GULP. The article also went on to say how intervals should be done on both flat and hills, not just hills as you can cheat using hills. Intervals on the flat are good for TT’ing, sprints and solo break aways.
I’m currently using sufferfest and the turbo for intervals due to the dark/ice, so its around 4mins of TT effort and 3 mins of climbing effort and then 3 min rest for an hour. Its nasty! I nearly puked at the end of the first one!
I have 4 races in March then i’m racing twice a week for about 8 weeks before settling back into once a week…training will no longer be required from the end of March! 🙂
