The e-Semi de Paris is the free e-race of the Harmonie Mutuelle Semi de Paris. The concept is to run 21 km with the partner of your choice between 6 and 10 September —the perfect opportunity to challenge a friend, a relative, your better half or a colleague from work. You can run together or separately, whenever suits you best. You just need to run a combined total of 21 km!
