Den Store Styrkeprøven - The Great Trial of Strength. One of cycling’s real classics. Feared and loved by riders for over half a century. Nothing comes close to completing this race.

From 1967 until 2020 we have witnessed 121 100 rides from Trondheim to Oslo or 61,06 million kilometers alternatively 1 523 circumnavigations around the Earth.

We welcome you to the 54t edition of Styrkeprøven and promise you a race that will continue in the spirit of 1967, offer improvements from 2019 and as always present one or two surprises.

The start in Trondheim

The start in Trondheim takes place in Trondheim, just outside Trondheim District Court in the Centre of Trondheim. The address is Munkegata, 7013 Trondheim. 

Selection of Start Groups

The riders in Styrkeprøven will rank and place themselves in Start Groups according to an expected time budget for the race. We would like to stress – select wisely and do not select groups with a lower time budget than you can manage. The ride will be a lot harder if you do so. At the same time the start groups with the largest budget are for those who actually need it. 

We have individual start groups reserved for Large Teams or Clubs. If you or your group would like to book an individual start for your Team - please contact Styrkeprøven AS

If you plan on using more than 30 hours your natural startgroups are from Friday June 11th 21:00 hrs until 22:45 hrs. If you plan to ride at 16 hours or faster you enter from 04:00 hrs Saturday June 12th
