Every ride is different, therefore every nutrition plan varies on the type of ride you are intending. In addition to differing Calorie requirements and recommendations, there are some specific do's and don'ts. This page will look at the 6 common types of rides and recommend 4 different diet periods for each ride.
A few additional tips for those trips that will have long back-to-back days on the bike:
Train with long back-to-back rides. You can train for a single century by riding long once a week because the event calls for just one day of exertion -- and then you can rest. But to build the stamina for a week (or two) of daily rides you should train with several long, back to back, rides.
Replace those Calories in training. When you're maxing those training miles, you need to replace the Calories you are burning (and fluids too) to keep muscle glycogen stores intact. If you skimp, you run the risk of increasing your level of fatigue.
Respect your contact points. Keep your hands, feet and saddle area happy. Pain in any of those areas can ruin a good adventure. Think twice about using new gear.
Beware of overtraining. It's tempting to put in big miles to prepare for the week. Going too fast (and often) has its own set of risks. Train smart.
