Food and Drink
Like most sporting events there are always places to get food and drink, but usually at higher prices. These are mainly within the circuit, although some sites do have bars that also serve food. Most campers will prefer to prepare their own food. Typically, a good fry-up starts the day (or cure the hang over from the night/day before) and a barbeque at night.
Whatever you decide, you will need to consider whether you take the food with you or call in at one of the hyper markets in Le Mans. There are several hypermarkets within driving distance from the circuit. These also provide a good place to stock up on drink.
At Le Mans one of the hardest things to do it to keep the drink and food as cool as possible. Some groups will have a generator powered fridge, others will have managed to obtain ice at the supermarkets (this usually runs out very quickly). On some sites, there may be local traders that will supply ice. It is also possible to get French bread and patisseries.
We would strongly advise that you do not leave valuables in your tents, if you do need to leave valuables lock them away out of site in your car. Generally there are very few problems camping at Le Mans and a great spirit of camaraderie between fans from all nations and usually there are people around who will notice anything untoward. However there have been occasions where tents have been broken into but this is no different to most large events which will attract the odd unsavoury character.
What NOT to take
Speed trap detectors, these are illegal in France, even possessing one is an offence.
