The Jotunheimvegen Ultra is the longest distance at the Skåbu Fjellmaraton and the only one that does not begin in Skåbu: you start at Bygdin Høyfjellshotell on Valdresflya and run the Jotunheimvegen towards the village. The long way down only reaches the valley floor, though, and the finish still has to be earned on Kamfossbakken.
The course runs point to point from Bygdin to Skåbu. It follows the Jotunheimvegen past mountain farms and along gravel road beside Vinstervatna before joining the marathon route. Much of it sits above 1,000 metres, and the opening plays that way: for more than 20 kilometres the road hovers around one height, broken only by short ramps, none of them as long as a kilometre.
The first serious climb starts at km 22 and takes a little over two kilometres to reach the day's high point at just under 1,200 metres. The course then drops back to its earlier level and stays there until about km 35. Only then does it really give up its height: by km 45 you have lost around 400 metres, most of them on the final stretch, and arrive in the valley at just under 700 metres.
Ten flat kilometres later the finale begins. Kamfossbakken climbs for more than two and a half kilometres at an average of nine percent. It alone supplies over a quarter of the day's roughly 800 metres of ascent, and the finish in the centre of Skåbu only comes once it is behind you.

Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
Almost the entire course is runnable, with steep ground making up only a small share. So your day depends less on any single climb than on the pace you allow yourself over the rolling first 20 kilometres. Everything feels easy there, and that is exactly where the aid stations are furthest apart: the first comes at around km 14, followed by gaps of more than ten kilometres. Plan this section around your own fluid and fuel.
The real trap sits beyond km 40. The drop into the valley rolls, your watch shows quick splits, and your quads pick up the bill. Run it relaxed with short steps, because those legs still have to carry you across ten flat kilometres on which the terrain gives you nothing for free.
The race is decided on Kamfossbakken. After this many kilometres, nine percent is a walking climb for most runners, and a strong, even stride costs less than a running attempt that falls apart halfway up. In the valley the aid stations come thick and fast. Use them early, because whatever you only take at the last one, around km 55, arrives too late for the climb.

Expect roughly five and a half to eight hours as an age-group runner. Because the terrain is even and largely runnable, that is mostly a steady aerobic effort without hard spikes. Your foundation is therefore long runs that you actually run, not mountain hikes in trainers.
Two sections call for specific work, and both come late. For the drop into the valley, put longer downhill stretches into the second half of your long runs so your quads learn to handle braking on tired legs. Add a flat section at easy running pace to those sessions: that exact shift from descending to level ground awaits you from km 45.
For Kamfossbakken, find a hill of eight to ten percent and place it at the end of your long sessions. Practise switching between running and brisk uphill walking until you have a stride you can hold for half an hour. What this asks for is strength endurance after hours on your feet, not speed.
You will spend a long time on gravel out there, so part of your long-run volume belongs on that surface. Train your fuelling as well: depending on the station you will find water, sports drink, bananas or cola, and your stomach should still accept them hours in. Practise carrying your own fluid too, since the early gaps between stations run to more than ten kilometres. With race day on 21 August, your longest sessions fall in high summer.
