Quick Answer
The key to fueling for MTB in Cusco is staying ahead of the faster glucose burn and slower digestion that come with altitude. You need to eat on a set schedule, prioritize simple carbs like bananas or oatmeal over heavy fats, and make electrolytes nonnegotiable on longer rides, since dry high Andean air can dehydrate you faster than you think.
Working out at about 11,152 ft (3,399 m) above sea level changes how your body responds. This fueling for MTB in Cusco guide is designed to improve your experience and reduce early fatigue.
Wondering how to fuel properly for MTB in Cusco? Our day tours are designed for riders who want authentic enduro adventures in the Andes always smoother when you understand the key to nutrition, energy, and recovery at altitude.
The importance of fueling right at altitude
Adapting your nutrition is essential for high altitude performance. A smart food and hydration strategy helps ensure the physical energy for climbs and the mental clarity needed for technical descents, while reducing the risk of sudden exhaustion.
Remember this:
Good nutrition boosts performance, but it does not replace acclimatization. If it is your first day, ride easy, hydrate well, and rest as needed.
How altitude affects your metabolism
The first physiological shift is lower oxygen availability, which speeds up your heart rate and increases carbohydrate use even at moderate paces. Digestion can also slow down because your body prioritizes blood flow to your legs and lungs.
Then add the climate factor, where dry air and intense sun in the high Andes can accelerate dehydration before you notice it. Although losing your appetite at altitude is common, your energy needs increase, so trusting hunger cues alone is a mistake.

High altitude fueling strategies
Your nutrition plan
The goal is steady energy without a heavy stomach. The strategy is to eat on a fixed schedule (e.g., every hour), making sure you consume small portions. Follow this basic framework:
| Timing | Before (Pre ride) | During (On bike) | After (Recovery) |
| Goal | Top off glycogen and keep digestion light. | Fast energy that is easy to digest. | Replenish muscles and rehydrate. |
| What to eat | Oatmeal, bread with jam, scrambled eggs (cooked without oil), coca tea. | Bananas, cereal bars, gels, soda crackers. | Trout, chicken, rice, potatoes, quinoa soup. |
Easy to find local options
You do not need to bring imported supplements. Cusco’s corner stores and markets have effective options:
- Banana: A local banana variety rich in potassium and easy to digest.
- Soda crackers or vanilla cookies: Simple carbs, ideal if you do not like gels.
- Coca tea: Traditionally used in the Andes, but clinical evidence is inconclusive and it does not replace acclimatization. If you drink it, have it at breakfast and always pair it with food.
- Local soups: Quinoa soup or light chicken soup are excellent after your ride because they provide fluids and salt at the same time.
A variety of nourishing foods you will find on your route.
Strategy by your discipline
- XC and Trail: Prioritize liquid calories or purees. If you eat solids, keep them to small bites.
- Enduro: Eat solids (bars, a sandwich) only on the climbs. Before dropping in, use fast sugar (gummies) to keep your reflexes sharp without feeling heavy.
- Downhill: Light snacks (chocolate, dried fruit) to maintain mental focus between runs.
- Multi day: Your recovery depends on a carb rich dinner (pasta, rice) so you wake up with energy for the next day.

Hydration and electrolytes
On long rides, plain water is not enough to replace lost minerals and sodium, increasing the risk of cramps.
If the ride lasts more than 90 minutes, add salts or electrolytes to a bottle. Use your urine color as a guide; dark, low volume urine means you need to rehydrate right away.
Common mistakes to avoid
Riding on an empty stomach
Tough at altitude; your energy stores burn fast.
Fats before riding
Fried foods take time to digest and can cause stomach issues.
Alcohol beforehand
It severely dehydrates you and can derail acclimatization.
