France seems to be full of nice little trail runs nobody knows about. For example Le Trail de la Source du Lison, or simply TraiLisOn, on October 23, 2011. Lison is the local river. Even the longest course available is only 45 km, but it comes with a respectable 2000 meters D+.

Unfortunately there are a couple of things that usually prevent me from taking part in races like this.
First, the start is located in the middle of nowhere - not easy to reach with public transportation. Like in this instance, you would have to travel to a small village called Nans-sous-Sainte-Anne (from there the organizers provide a bus to starting area). If could fly to Geneva in there hours without any problems, but I'm not sure I could ever find the race location!
Second, all races in France (and other Mediterranean countries like Italy and Spain) require participants to have a recently written permission from their doctor. In Northern Europe we do not really understand bureaucracy like this at all. Hmm, maybe that's why the European Union is falling apart. We go to the doctor only if we have some issues they can help with, not to get a useless piece of paper. But rules are rules, I guess.
Anyway, Arthurbaldur managed to run this race, and here is his video documentary. Beautiful scenery!
