Running, riding bicycles, doing an obstacle course and then a swim - phew!
Full title reads: "France. A Unique obstacle race. Competitors have to run, crawl and swim in annual race held on the out-skirts of Paris."
Competitors start running off at beginning of race - most of them look like fairly young men. The competitors finish the running section of the race and collect their bicycles. They ride off. Various shots of cycling section.
Competitors climb over a high wooden fence and then crawl under various obstacles (it is a bit like and obstacle course in army training).
The leading competitor runs along the river bank and at the appointed place dives into the water and begins to swim.
N.B. It looks rather too tiring for my tastes. MD.
