Trail 91 km is the longest course at Ecotrail Bergen, and the only one that needs some 27 km just to reach the start line of the next distance down. Prepare for just over 4,000 metres of climbing, and above all for the hardest climb of the day arriving when you have already been out for hours.
The course starts just 14 metres above sea level and runs point to point into the finish where all five distances end. The first 27 km or so belong to it alone. Three times the trail rises past 200 metres and drops well below it again. By the time it joins the next shorter route, some 1,000 metres of climbing are already done.
Then comes the section that defines this race. From km 31 the trail gains 438 metres in just over two kilometres. That averages around 20 percent, and at the top, at about 640 metres, you reach the highest point of the course. It stays up there for several kilometres before falling back below 100 metres by km 47.
Three more climbs of at least 169 metres each follow by km 60. Just past km 65 you meet a shorter course, and it leads up once more to 575 metres. Ecotrail Bergen, set up by its organiser as an environmentally conscious race, is built this way: each shorter distance is the closing stretch of the longer one. At the very end the trail drops from just under 300 metres to close to sea level within a few kilometres, with one small rise before the finish.
| Start | Length | Ø | Max. | Gain | Cat. |

| km 1.2 | 1.2 km | 12.7 % | 29.6 % | +146 m | Cat. 4 |
| km 19.4 | 0.9 km | 14.7 % | 27.6 % | +132 m | Cat. 4 |
| km 29.1 | 1.4 km | 9.3 % | 21.8 % | +133 m | Cat. 4 |
| km 30.8 | 2.1 km | 20.6 % | 45.4 % | +438 m | Cat. 2 |
| km 48.4 | 1.7 km | 10 % | 21.1 % | +169 m | Cat. 3 |

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 first 27 km are a run-up, even if they do not feel like one. Around a quarter of the total climbing sits there, and none of it decides anything. Run it easily enough that at the foot of the big climb at km 31 you feel as if you have only just warmed up.
That climb is the first trap. At around 20 percent it lasts long enough to push your heart rate somewhere you will pay for that evening. Walk it at a pace you could hold for another hour, and treat the kilometres at 600 metres as recovery rather than a chance to bank time.
The race is decided later. After the low point at km 47 the climbs come close together. From km 66 the trail then takes you one last time from low down all the way to 575 metres. If you can still climb steadily there, you will also get down the last steep descent under control. More than 40 percent of the course runs downhill, and hard braking early on leaves you without quads at the end.

Age-group runners can expect around 14 to 21 hours here, and on a day like that endurance counts for far more than any speed session. The effort is almost entirely aerobic and swings constantly between climbing and braking, since only about a seventh of the course is close to flat.
Two things decide your day. The steep climb after just over 30 km has to be hiked without overreaching. And after more than 65 km you must still be able to climb almost another 500 metres. Neither comes from running volume alone.
Build your long sessions so the hardest climbs come late, and on some weekends run two long days back to back. Steep hiking deserves its own session: long repeats on very steep slopes at a pace you can sustain. Add downhill running on tired legs, because the last big descent only begins after about 85 km.
The race falls in late June, which puts your longest sessions in May and the first half of June. Use them to practise eating and drinking while hiking uphill as well. On a course with so little flat ground there is hardly another moment for it, and over this many hours that skill is as much a part of training as any climb.
