The Trophée Vallée du Flon is a 13 km race held in Le Flon, in the Swiss canton of Fribourg, during November. It is classified as a "Populaires" event, intended for recreational runners rather than exclusively elite athletes.
The race begins in Le Flon and also features Nordic Walking, a category for schoolchildren, and an adapted race. November weather in the region typically brings cold conditions, with temperatures ranging from 2°C to 7°C and average precipitation around 45 mm. This makes it a local race suited for the cooler season, distinct from a quick summer event.
