The number of ultra trail runners is increasing annually. The amount of organized ultra trail running events has grown over the past few years throughout the world. Runners often cite less impact stress compared to road running, as well as the landscape and non-urban environment, as primary reasons for preferring trail running. This move to nature is also reflected in a large increase in competitors in non-traditional/off-road triathlons and adventure racing over the past years.
