Trail races in Auvergne-Rhône-Alpes — August 2027
The world epicentre of high-mountain trail: Chamonix, at the foot of Mont Blanc, is the birthplace of the UTMB; Annecy, by its turquoise lake, hosts the Maxi-Race. Brutal elevation gain, glaciers, and some of the most photographed alpine landscapes in Europe.
2 races scheduled
Climate in Auvergne-Rhône-Alpes: The safe high-mountain window runs from June to September, when passes and ridges are free of snow. July and August concentrate the bulk of the calendar, with UTMB in late August and Maxi-Race and Marathon du Mont-Blanc in June-July. Outside that window, snow can close the highest sections even in midsummer during years with late thaw.

Tips for running in Auvergne-Rhône-Alpes in august
If running in northern Spain, do not be complacent: fog and rain can appear even in August on the Cantabrian coast.
Carry salt tablets or electrolytes: in August the risk of hyponatraemia is real if you only drink water.
Make the most of cool hours for training: 7-10 AM and after 7 PM are the optimal windows.
