If you think that riding theRace Across Americais just a matter of legs and head, you have never tried to assimilate 12,000 calories while pedaling at 104°F (40°C). At RAAM, the cyclist is not just an athlete, they are a thermal internal combustion engine. And that engine needs a frightening amount of fuel so as not to seize along the 3,000 miles of the route. Managing nutrition and avoiding the "closed stomach" is the real challenge that decides the race.
1. The Energy Requirement: 12,000 Calories a Day
A cyclist engaged in RAAM consumes between 10,000 and 12,000 calories every 24 hours. For comparison, it is equivalent to the average consumption of a man for three full days. Introducing this amount of energy while constantly in the saddle and in motion is a titanic undertaking. The stomach must work under continuous kinetic stress, with blood being constantly diverted to the leg muscles instead of the digestive tract.
2. The Curse of the Mojave: Hydration Management
In the Arizona desert, sweating can exceed 1.5 liters per hour. The air is so dry that sweat evaporates instantly, giving the cyclist the illusion of being dry. It's a deadly trap. If the hydration rate drops by even 3%, performance drops by 20% and the risk of acute renal failure becomes extremely high.
The Crew monitors every single milliliter of fluid introduced and expelled. Hypotonic solutions rich in sodium, potassium, and magnesium are used to prevent hyponatremia. Pure water, in these extreme conditions, is not enough: it would excessively dilute the mineral salts in the blood with very serious neurological consequences.
3. Liquid Nutrition vs Solid Food: The Kinetic Compromise
For the first 48 hours of the race, the rider can feed on light solid food (rice, milk buns, bananas). But as fatigue accumulates, chewing becomes tiring and the stomach rejects fibers. The race then shifts toLiquid Nutrition.
- Maltodextrins and Cyclodextrins:Complex carbohydrates with gradual release dissolved in the water bottles. They allow introducing up to 90-100 grams of carbohydrates per hour without weighing down the stomach.
- Branched-Chain Amino Acids (BCAAs) and Liquid Proteins:Essential for slowing muscle catabolism. In non-stop races, the body literally tends to "digest" its own muscle fibers to produce energy if it does not receive a constant supply of proteins.
To vary the taste and avoid psychological rejection of sweetness (the so-called "sugar fatigue"), the crew alternates sweet bottles with savory solutions, such as warm filtered chicken broth or savory liquid puree.
4. Closed Stomach Syndrome: Emergency Solutions
The real nightmare of every Crew Chief is gastric block. When the stomach closes and rejects any food, the clock keeps ticking and glycogen reserves are depleted in less than two hours. If the rider goes into "hunger flat" in the desert, the race is compromised.
In these cases, the crew adopts emergency protocols: immediate reduction of the cyclist's heart rate to draw blood back to the digestive system, administration of natural digestive enzymes, and small sips of fresh carbonated sugary drinks to stimulate gastric motility.
5. Conclusion: The Fuel of Victory
Nutrition at RAAM is not a matter of diets or pre-race charts: it is a dynamic and flexible management that adapts to external temperatures, the rider's mood, and the response of their digestive system. The Annapolis medal also belongs to whoever, from the support car window, knew how to hand over the right bottle at the right moment, keeping that fantastic human engine running.
