Once you have organised your trip to Chamonix for the UTMB®, there are several key aspects of the race itself to get to grips with: the weather to anticipate, nutrition and aid stations, support crew rules, and sleep management during the event. A solid understanding of these points will help you approach the start line feeling calmer and better prepared.
Chamonix weather in August
Late August in the Chamonix valley generally enjoys mild weather, but conditions in the high mountains can change rapidly and will affect both your race kit and your hydration strategy during the effort. Find our tips to help you prepare in our article Chamonix weather in August for the UTMB®.
Race nutrition
Knowing the location of aid stations and their type (liquid only, or liquid and solid) will help you better plan your stops and personal nutrition strategy. Find the full details in our article Nutrition and aid stations during the UTMB®.
Support during the race
The authorised support rules along the course will help you plan your meeting points if you have a crew. Find all the rules, zones and shuttle details in our article UTMB® Support: the rules, zones and shuttles you need to know.
Sleeping during the UTMB®
Managing sleep on an event as long and demanding as the UTMB® requires preparation well in advance, starting during your training phase, to get your body used to fragmented sleep on race day.
