Source: Iconosquare
Nepal–Taking place in the famous Himalayan Mountains, this race is 153 kilometers over 6 days. You also need to be aware that the altitude is an extreme factor in the race. Lots of rocky terrain, and sometimes snow await racers on this trek. It’s divided into different stages, and snacks, meals, and water are provided by the race sponsors. So at least you don’t have to carry as much with you, but you still have to have your sleeping material and anything else you might need to complete the race.
