Video. World record set at extreme Antarctica Ice Ultra race

The Antarctica Ice Ultra is an endurance race that challenges athletes to push their limits.

The competitors faced extreme conditions, with temperatures starting at -17°C and plummeting to -25°C, accompanied by strong katabatic (downhill) winds.

For safety reasons, the race was held on a 4.2km loop around the Ultima base camp, allowing runners to take breaks in a refectory tent for food and water.

Americans Paul Johnston and Roberto Sembiante set a new world record in the 100-mile (182 km) race, finishing in 23 hours and 22 minutes.

In the 100km race, China’s Yusheng NI completed the course in 10 hours and 40 minutes.
