Every January, more than 3,000 people take part in one of the most difficult races on Earth: the Tough Man Competition in the U. K. The participants run, swim and climb around the 15 km course. But this race is not normal. These runners have to crawl through tunnels, run across a field of nettles (荨麻) and jump over fire. What’s more, the competition takes place in January when temperatures are freezing. People travel from throughout the world to participate in it.

The competition is quite dangerous and every year there are accidents. Injuries like broken bones and cuts are quite common. One-third of the participants can not complete it. Runners have to be very athletic and most people train all the year to prepare for it. There are similar events, but this is the first one in the world. Many people do the competition because it is so famous. Every year the organizers change the events and add new things. This means that the competition stays thrilling and challenging, so people go back year after year.

First, the participants run 1km along a muddy road. Next, they crawl under low nets on the ground. After the nets, the runners jump off a high platform into a lake and swim for 1km.
