On 21 September, take part in the Challenge Mobilité by opting for an environmentally friendly way to get to work – on foot, in a carpool, by bike or on public transport – it’s entirely up to you.

Some 1411 companies have already signed up for the Challenge, which is an initiative of the Auvergne-Rhône-Alpes region where the French parts of the CERN site are located. This is the 11th time the event is being run, and the 7th time CERN has taken part.

So, on 21 September, why not hop on your bike, don your running shoes or consult the bus timetable? And if you want to go a step further, try out some of the highly original extra challenges suggested here (in French only).
