You are yourself responsible for downloading and following the correct route. 
For FV100 and FV150 riders we strongly recommend that you download the course in sections to your gps device and load the new section when you have finished the previous. 
This will prevent you from getting confused in the places where the race track crosses itself or has the same trail in-and-out.
It's your responsibility to follow the correct route.

Have a look at Tor Hovland's recap of the FV2023 here:


FAT VIKING is a WINTER ULTRA ENDURANCE event under somewhat more "controlled" circumstances than the Iditarod Trail Invitational. 

The race course runs on snowmobile tracks, dogsledding trails, snowcovered roads and cross country skiing trails around Geilo/ Skurdalen/ Dagali. Checkpoints are inside a heated building where basic food (oatmeal) is offered along with the opportunity to rest. Several "bail out options" along the route are available in case of emergency/ abandoning the race. 
The route changes from year to year (mainly due to snow-conditions, but also to keep you on your toes and to show you more of the beautiful area).

Fat Viking is a non-commercial Geilo IL (Geilo Sports Club) event organized by the "FAT VIKING SOCIETY".
We organize this without getting payed. We do it for the love of the sport. Our effort is all worth it if YOU come back with a smile on your face, with an adventure behind you and a lot of stories to tell.

Please read the ABOUT information, the MANDATORY GEAR list and RACE RULES before entering.

Race distances 50km - 100km - 150km. 
All distances start together.
The 50km distanse finishes at CP1 (we will find a way to transport riders back to Geilo).
If you register for the 150km/ 100km but only make it to CP1 we will still call you a "finisher" (an FV50 finisher). The same applies if you enter the 150km event but only ride the 100km distance. You will of course not count in any ranking or the competition itself.

This is a chance to prove to yourself that YOU ARE STRONGER THAN YOU THOUGHT.

Please ask your questions in the Fat Viking Facebook group. If absolutely neccessary you can drop Nina a line (se contact details below).

To be a Viking or to become one. Human endurance and human resilience*. 150km of winter racing. A journey within yourself.
*(definition of resilience: "the power or ability to return to the original form, position, etc., after being bent, compressed, or stretched)


Geilo Aktiv (Nina) arranges a training camp prior to the race (Monday to Wednesday). This is a course about safe and efficient winter travel where you learn and practice the essentials.
Join the 3-day training course if you want to learn more about winter riding
