Australian 'rogaining' is extreme orienteering, with a few extra differences. Teams of 2-5 people have 12 or 24 hours to locate as many checkpoints as possible, hidden in a mix of bush, forest and farmland, using only a map and compass. The winners typically cover 100+ km through rough terrain, carrying all they need, barring refills at a few water drops. Variations include city 6 hour events, 12 hour night events in mid-summer, and the 'Snowgaine' in the Australian Alps. In recent years the sport has gone international and world championships have been held in North America and Australia.
My personal best effort involved moving continuously for 23:50 of 24:00 hours. We covering around 100 km, dodging wild pigs, emus and electric fences, sometimes in darkness, fuelled by a vegan diet, which I prepared and ate on the move. We ran for half of the 1st day, walked all night and were shuffling like old men by the end! We no longer bothered finding crossing points but walked straight through streams. Several of my toe nails fell off. My hair however, thankfully grew no longer.
