« Fantastic organisation, bravo! It's great to just be able to concentrate on your running, secure in the knowledge that everything else is taken care of, down to the smallest detail »

Comments from previous participants

« Great organization despite so many participants. Perfectly managed service after the finish line, including potato chips :) Crowds and live bands along the race giving an extra motivation and inspiration for runners. Overall a massive event worth to come from abroad. Merci Paris!»

Comments from previous participants

« My first half-marathon, and a great experience. Very far from what I had hoped to do but the stopwatch wasn't what mattered for this first run. The bad weather was quickly forgotten thanks to great organisation and volunteers working full throttle to help us. Decent food...in short, if it weren't for the rain and the nasty hill that really took it out of me, everything would have been perfect! Looking forward to next year! :) »
