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 Hardanger fjord to the local town, Eidfjord.
[1] After transition two (at Austbygdi, 190 m above sea level), the competitors then run 42.2 km of which the first 25 km (to Rjukan) are flat and following this they end up climbing the local mountain, Gaustatoppen, 1,880 m above sea level.
[1] 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.
Those that do not make the cut-off time but complete the distance on a lower alternative route are given a white finishers top.
After the race, the safety crew decided to start the "Cold Water Research Project",[3] which will continue for several years including one or more PhD degrees in progress.
