The course

The route

Point-to-point from Trondheim to Oslo, around 540km with roughly 3,500m of climbing, almost all of it in the opening 120km. From there the route settles into rolling-to-flat river valleys and lakeside main roads, with a pre-dawn start that sends most riders through the short Nordic night.

Intervals.icu

540km, mostly after the hills

Typical sessions

Around 3,500m of climbing crammed into the first 120km, tempting fresh legs into a decisive early mistake.

Hundreds of kilometres of rolling-to-flat valley road where wind and monotony grind you down.

A day of anywhere from 13 to 30 plus hours, running through the pre-dawn start and the Nordic night across a big temperature swing.

Fuelling for 20 hours or more, where small hourly deficits compound into a bonk.

What your weeks look like

Typical sessions

Progressive long rides building from 200km toward a 350 to 400km peak, the core adaptation.

Back-to-back big weekends, 200km Saturday and 150km Sunday, to train cumulative fatigue.

Fuelling rehearsals on any six-hour-plus ride at 60 to 90g carbs an hour, on your exact race products.

Night rides with lights and layers to rehearse pacing and kit in the dark.
