ANALYSE YOUR PERFORMANCE
You'll be able to analyse your results down to the smallest details (route simulator "Relive your race") and compare your performance with others runners tomorrow.
The Real Time corresponds to the calculation between the moment that you cross the start line (on carpets) and the moment that you cross the arrival line. It is the most accurate time for the the performance bacause it is your real race time. However it is not used offially by the Athletic French Federation, the best runners are always at the start peloton. They do not have therefore a delay between the gun shot and when they cross the start line. The runners who are at the end of the peloton (amateurs) have a more significative waiting time.
