I'm just about to put a deposit down for a 5 day ride across the Pyrenees next September (following a similar route to the Raid Pyrenean). Any tips for training for consecutive days of heavy climbing? I'm 6'4" and 80kg so not exactly built for the terrain! So far, I'm just planning on getting a lot of miles in plus a few repeats up and down Alpe du Zwift over winter/spring, and then ramp up the length/stress in later spring and summer. Just as background, mileage this year is 3750 or so, 220k feet climbing, and the biggest volume is probably 250 miles over three rides in four days, so I've got a reasonable base to start from. I'm not aiming to be particularly rapid, just to be fit enough to enjoy the trip.
