Boosting your power output is vital for any form of climbing – but it’s especially true for endurance climbs, which require serious wattage if you’re to tackle them with gusto. Many of the world’s top pro riders work on boosting their climbing powers by riding long and sustained climbing intervals in training, using bigger gears than normal and at a sub-threshold intensity. This isn’t something you should attempt until you’ve reached a decent level of climbing fitness, as it could prove counter-productive. Don’t go with a crazy big gear either, you need to be able to churn it around without wrestling with your bike. Ideally you want one that’ll force you to a high output level of around 60rpm. These are intervals, and you can vary their lengths depending on the available terrain and your fitness levels. Anything from three minutes on and three minutes off on a small, local hill, to a prolonged 30-minute effort up Alpe d’huez, or even a tough home trainer session will reap huge rewards. Be sure to focus on your technique too, using them to maximise your pedalling efficiency – iron out the dead spots in your pedal revs – and avoid bobbing around.
