What racers and reviewers say
- SlowtwitchRaced 2022 · article · Positive
First-person account of a cold, wet, windy year. Water about 15 °C (59 °F) at the start, record-cold wind chill on the bike, numb hands and feet requiring crew help, then a joyful Zombie Hill climb lined by locals. Travel delays meant an 18-hour drive and almost no sleep.
“Comfort will always be waiting for you.”
- Slowtwitch (Jenny Gowans)Raced 2008 · article · Positive
Winner's report from an early edition: cold, clear, slightly salty fjord, current against her, cold driving rain on the bike and an eventful run to the 1,880 m (6,170 ft) summit. Credits her crew as decisive and calls the swim one of her best racing experiences.
“all finishers are winners”
- Team ZERORaced 2017 · blog · Mixed
A DNF story: dark icy start, calf cramps, a storm on the swim return, and removal from the bike around km 40 for hypothermia. Highlights how quickly cold turns dangerous even for a prepared athlete.
- Triathlon Magazine CanadaRaced 2013 · article · Mixed
Report on the 11th edition: overnight gales and lightning, headwinds, heavy rain and fog on the bike. Lightning disabled the cable car, so finishers had to walk down an extra 5 km (3 mi). Winner Markus Stierli called conditions perfect.
“I guess, that's why its called Extreme!”
- SlowtwitchRaced 2016 · article · Mixed
Short report with photos: rain and cold on the bike, steep climbs and long descents, lights and reflective vests mandatory early, then a flat start to the run that becomes a rugged climb to Gaustatoppen.

Second-place woman describes a comparatively warm 16 °C (61 °F) swim with a bonfire to aim for, a tunnel-heavy opening climb before the scenic plateau, and a 20 km (12 mi) flat run along the lake before a boulder scramble. Crew handovers were vital; the black shirt is a treasured prize.

Thread on lodging and tactics: race hotel in Eidfjord fills fast, alternatives across the fjord, separate finish lodging near Gaustablikk or Kvitavatn, crews cannot reach riders until ~40 km (24.9 mi), and most athletes hike Zombie Hill. Tips on aero setup and brick hill repeats.
