The Nordmarkstravern's classic distance crosses Nordmarka from end to end: 30 kilometres of trail and gravel road from Stryken to Kringsjå and Sognsvann. No single hill decides it. Eight short ramps spread across the middle 20 kilometres wear the legs down one at a time, and the plan has to account for all of them.
The first five kilometres out of Stryken carry no climb worth the name; after that the rolling core of the course begins. Between km 5 and km 8 three ramps come in quick succession, the last of them short but close to ten percent. At km 10.4 the trail climbs for almost another kilometre before the hardest section: from km 14.4 it rises for 850 metres at an average of just over ten percent, considerably steeper at its worst.
From there the course relents. A climb at km 19.4 with steep pitches and a short rise at km 25.5 are the last tests before the trail drops toward the finish. Over the point-to-point route you lose slightly more height than you gain, with a little over 600 metres of climbing in total.
The running surface mixes paths and gravel roads through the forest north of Oslo. The start is out at Stryken, the finish on the edge of the city at Kringsjå and Sognsvann, where the shorter distances come in as well. The race is held at the beginning of September.

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.
The flat first five kilometres invite a pace you pay for later. Run them deliberately easy, because from km 5 the climbs come one after another and none is long enough to recover on. Take the short ramps at a steady effort rather than a steady pace and use the stretches between them to settle your breathing.
The race is decided between km 14 and km 21. The steepest ramp at km 14.4 costs most if you arrive with your heart rate already high; a brisk hike there is no weakness. Five kilometres later the next steep climb arrives, and whoever can still run after it gains time over the last nine kilometres.
The trap is the run-in. It drops away and tempts you to let go, but after more than 25 kilometres of path and gravel, tired legs on a descent are the most common cause of a misstep or a fall.

For most age-group runners the course means somewhere between two and a half and four hours of work. The base is aerobic, broken by short hard efforts on the ramps that usually last only a few minutes but weigh more heavily after the first third.
What decides the day is whether you can still climb a steep pitch with some force after 14 kilometres. Build long runs that put the hills in their second half, and practise switching between running and brisk hiking on steep forest sections. Repeats of two to four minutes uphill with easy jogging between them match the pattern of this course better than one long even climb.
The surface needs its own preparation. Run on paths and gravel regularly so ankles and feet are used to changing ground, and practise downhill running at the end of long sessions, since the run-in tests exactly that.
In September a race of this length is also a fuelling question. Test in training what you can still stomach after two hours, and do your long runs in the kit you plan to race in.
