Dirty cheeks, wet hair and hot eyes in which you can see pride and strength. These are portraits of typical OCR (Obstacle Course Racing) participants. Thousands of athletes take part in the race: employees, students etc. Each of them wants to face their own weaknesses, both mental and physical. The athletes cover the route from 3 to 21 kilometers, packed with dozens of obstacles (mud baths, climbing walls, crawling under the fences, climbing the rope). One third does not reach the finish line.
