ASICS Beat the Sun 2016, Nature's Toughest challenge, took place on June 21st in Chamonix. 8 intercontinental teams took part in a relay run around Mont Blanc on the longest day of the year. The objective: to circumnavigate the massif Mont Blanc between the sunrise and the sunset. With only 2 of the teams, Europe North and Europe South, running faster than the sun it was once again clear that Beat the Sun is not called nature's toughest challenge for nothing.
