I tend to naturally stay seated when climbing – maybe it’s growing up on the track, as when you’re riding fixed gear you hardly ever get out of the saddle – and that’s generally the most efficient way to climb.
I try and stay in the saddle, only standing to break up the rhythm or on a particularly steep section, treat a climb like a time trial – it’s you against the climb.
Having a good a cadence and a good position on the bike definitely helps to be more efficient. Make sure you’re not rocking and rolling on the bike, open your chest and concentrate on your breathing.
Try and keep your legs spinning, with a cadence of around 80 to 90. I sometimes get up to 100 but that’s pretty fast and you’ve got to train to get used to that speed.
Just make sure you keep turning your legs over in order to stay on top of the gear.
