    Why Fuego XL is challenging

    • Time on course

      A ride this long needs a plan you can repeat for hours, including what happens if you slow down on the climbs.

    • Elevation change

      About 11,100 feet of elevation change raises the chance that a flat-road carbohydrate rate will feel wrong. Adjust for your climbing pace rather than copying a road-race script.

    • Unpublished detail

      Until the organizer locks the map, plan with distance, elevation, and your own pace. Do not assume last year’s feed zones.

    Fueling challenges & strategy

    General, evidence-based guidance. Numbers should always be personalized to sweat rate, body mass, fitness and weather.

    Carbohydrate range

    A common endurance starting range is about 60–90 grams of carbohydrate per hour for trained riders who have practiced that rate. Some riders tolerate less. The right rate is the one you have rehearsed, not a guarantee of performance.

    Fluid and sodium

    Fluid need often falls around 400–900 milliliters per hour in mild conditions and can be higher in heat or for heavy sweaters. Sodium often lands around 300–800 milligrams per hour. Use your sweat rate, not a festival average.

    What this is not

    These are planning ranges for healthy athletes who already tolerate the products. They are not medical advice, and they are not a promise that you will finish.

    What most riders get wrong

    • 01

      Borrowing the XC plan

      Fuego XC is a different race the next day. Its shorter duration does not prepare an XL bottle schedule.

    • 02

      Treating a cutoff rumor as a plan

      Official timing notes belong on the organizer’s site. This guide does not publish cutoff times.

    Why generic fueling plans don't work for Fuego XL

    Two riders on the same start line can need very different fueling. FTP, target finish time, body mass, sweat rate, temperature, altitude adaptation, nutrition products and race goals all change the answer. A generic 60 g/hr recommendation is a starting point, not a plan.
