Norseman triathlon

The Norseman Xtreme Triathlon is a non-Ironman branded triathlon, point to point, race held in Norway annually. The distances are equivalent to those of an Ironman race with the swim starting from the loading bay of a car ferry, through the water of the Hardangerfjord to the local village, Eidfjord. At Eidfjord the competitors transition onto their bikes and then cycle 180 kilometres (110 mi) through the mountains, the first 40 kilometres (25 mi) of which is uphill (reaching 1200 m above sea level). After transition two (at Austbygdi, 190 m above sea level), the competitors then run 42.2 kilometres (26.2 mi) of which the first 25 kilometres (16 mi) (to Rjukan) are flat and following this they end up climbing the local mountain, Gaustatoppen, 1,880 m above sea level.

The race is "unsupported" so competitors need to have personal back up crews that follow them with cars to provide them with food and drink. The support crews also have to accompany their competitor up the final mountain climb due to the inherent dangers of being highly fatigued on a mountain. During this final mountain climb competitors are required to carry a backpack containing emergency food and clothing should the weather turn, whilst they are on the mountain.
