Choosing your race
The Mont-Blanc Marathon races take place in the mountains, on technical trails that can be quite steep. To take part in these races, it is recommended that you have good experience of mountain running, are comfortable on all types of terrain and can run independently for several hours. We remind you that it is generally considered that 100m of positive ascent corresponds to 1km of additional running.
For example: the 42km Mont-Blanc race has a positive altitude difference of 2540m, which corresponds to a distance of 42km + 25km, i.e. 67km. We therefore recommend that you take into account the difference in altitude before registering for a race.
