In other words an average speed of 14.1 km/h!
The Paris Marathon is quite unique in being the first in the world in terms of number of runners completing the race in under three hours. A pace of 4 mins 15 secs per km is only for highly trained athletes. The hares have personal records of 2hrs 21mins and 2hrs30mins. They run at a steady pace to ensure the mythical barrier of three hours is broken. Refreshments are taken on the run.

In other words a pace of 4 mins 35 secs per km (13 km/h). Training is very serious, with experienced hares who ran in the last five editions of the race. Time lost for refreshments is minimal. The time gained at the start thanks to the enclosure is helpful in attaining this objective.

At 5 mins per km (12 km/h). Experienced hares from the last five editions of the race slow down at each of the refreshments points, which is of capital importance. They return to a steady pace in between each refreshment point.

5 mins 20 per km (11.25 km/h): this is the pace of the majority of Marathon runners.
The most difficult thing is not to crowd up around the hares and to remain at a reasonable distance behind the balloons.

At 5 mins 40 secs per km (10.5 km/h) the mythical barrier of 4 hrs is for you. Take care over the first half of the race.
There are stops for refreshments and you will receive a lot of encouragement from the hares at each stop.

At 6 mins 25 secs per km, the pace is 10 km/h, including stops for refreshments; the hares provide psychological support to help runners keep to a steady pace. Strong determination will do the rest.
