This series of images was taken over a very long race day at the adidas INFINITE TRAILS World Championships 2019, with the athletes starting the race at 4am and the winning team finishing in just over 13 hours. This race format sees runners compete on an epic trail running course as relay teams of three for the adidas INFINITE TRAILS world title. The runners complete a joint Prologue to determine their starting position for the relay, which commences with a chasing start. Each team has to tackle a demanding, 120km+ long course through the mountains of Bad Gastein in Austria. There are three distinct loops, 20km, 60km and 40km that play to various running strengths. A team is victorious when all 3 members of their relay team have run the final kilometre and cross the finish line as a team.
