I thought I'd kick off this forum with a post copying
Form Nutrition's sound advice for sportive riders, published in the latest
Cyclefit newsletter:
Our Top ten Tips
- Avoid eating up to 2 hours before the ride; your fuel tank should already be filled up from breakfast and the preceeding days' good nutritional intake.
- Avoid going into the red (the point at which you can not speak to the rider next too you) too much - the harder you work as a percentage of VO2 max, the greater the proportion of your limited stores of glycogen that will be used for energy.
- Aim to consume 1g of carbohydrates per kilogram of body weight per hour of riding.
- Aim to take in a minimum of 500ml fluid per hour of riding.
- Consider low GI foods early in the ride.
- Aim to consume 200 grams of carbohydrate the morning before the ride.
- Remember there is a 2 hour window of opportunity after the ride where consuming carbohydrate and protein will most effectively replenish stored glycogen, help repair muscles, and aid recovery.
- Continue to eat carbohydrate all evening after the ride, but be careful with the fat intake.
- Don't forget to do plenty of drafting, avoid time trialling the whole ride.
- Consider: Sports drinks, bars, gels, sandwiches, bananas, raisins, dates, jelly babies, cereal bars, figs to take during the ride.
And I'd like to add a tip of my own: #10 above points to the importance of consuming a variety of textures to keep you interested in feeding on the bike, but even with a combination of drink, energy bars and real food, after 4 or more hours sweet things can become pretty sickly and off-putting. Consider something savoury, too: a marmite bagel, ham & cheese roll, or a handful of salted peanuts will provide welcome calories, sodium, and free fatty acids to fuel the aerobic energy system.
