Cleanliness :

La Diagonale des fous, le Trail de Bourbon and la Mascareignes are clean, eco friendly races :

Paths and refreshment areas must be left as clean as they were before the race. Eat and drink within the refreshment areas.
Contrary to what one tends to believe, biodegradable stuff (orange peelings, bits of bread..) pollutes. Rodents feed on them and they are a nuisance.
Anyone caught polluting or dirtying the paths will be sanctioned according to by-law 17 of the Book of Rules.
