Consistent intake on the bike

Cycling allows for higher fueling rates than running since there is less GI jostling. Set a timer for every 15-20 minutes and aim for steady intake. Bottles are easier to manage than gels at high speeds.

What to Expect at Vino Fondo

Vino Fondo is a Century Ride (100 mi) century ride (100mi) held in Defiance, MO, US. Based on 5 years of historical weather data, athletes can expect median race-day temperatures around 73°F.

Temperatures at Vino Fondo typically range from 65°F to 82°F. The upper end of that range crosses into moderate heat risk. While not extreme, sweat rates will be elevated and athletes who under-fuel on sodium or fluids may feel it in the later miles. A dialed-in hydration plan makes a real difference here. Humidity is also a factor here, with levels reaching 81% on warmer days. High humidity impairs sweat evaporation — your body's primary cooling mechanism — so perceived effort rises even when temperatures look manageable on paper.

Cycling events allow for higher fueling rates than running since there's less GI jostling. Most riders can comfortably handle 80–100g of carbs per hour, delivered through a mix of bottles, bars, and on-bike snacks. Set a recurring 15–20 minute timer as a fueling reminder — it's easy to forget when you're focused on the road.

We do our best to keep race details accurate and up to date, but things can change and occasionally we simply get something wrong.
