I f*cking hate indoor interval training!

Pacing does though. Dunno if you're on fixed, but I find seated spinning on the generally less steep lower slopes of hills forces you to save yourself for when you have to stand up and cane yourself on the steep bits, which is where the races are won.

Boardman said he always used to win HCs in the second half of the climb.

Never start like a nutter – Boardman often won championships where he was slower at the half way point. Only in the last half would he really go into the red. It takes a lot of discipline to hold back until the right moment and then really go for it.
