On rollers, common people change resistance by changing gear. Obviously, as you’re a well brought up girl, you’ll be on fixed, so the only way to do interval sessions is to spin like hell. I thoroughly recommend it – where on the road do you get the chance to do 180rpm (250 if you’re Jamie Staff, apparently)? Rollers are also kinder to tyres and frames, as they don’t impose substantially different loads from road cycling. As a fixed rider, you already demonstrate a pursuit of cycling purity, so it’s a terrible shame to corrupt that with these silly toys designed for people who aren’t quite ready to have the stabilisers taken off their bike – it has to be proper, 3 drum rollers.

I haven’t tried them myself, but the design of Trutrainer rollers gives a more realistic simulation of load against speed, so you won’t need to change your gearing, otherwise I’d suggest increasing your gear by 20-25% compared with road use for normal Tacx rollers.

None of this will alter the fact that it’s still terribly boring, so doing intervals or ramps or some other structured session is the best way to stay awake – no sane person can do base miles on either rollers or a trainer.
