How Hard Is Blefjells Beste 96km — and What Does a Race Built on Two 9km+ Climbs, a 22:00 Night Start, and Norwegian Mountain Weather Demand From a Runner When Gradient Is Not the Point?

Q: How hard is Blefjells Beste 96km, and what kind of difficulty does a Norwegian fell ultra with moderate gradients actually present? | A: Blefjells Beste is not a gradient race. The distance-weighted average uphill gradient is 8.51% — rank 309 of ~390 GPX-tracked courses in the DTR database, placing it among the more runnable 96km profiles in the catalogue. 308 courses climb more steeply; only ~81 are gentler. The Blefjell massif is Norwegian fell terrain: rocky plateaus and sustained rolling ridgelines rather than near-vertical mountain pitches. What makes Blefjells Beste hard is the combination of distance (96km), sustained long climbs (9.2km at 5.1% avg from the gun; 10.5km at 5.0% avg at km 55 on tired legs), and conditions: a 22:00 start sends runners into the Norwegian mountain dark for most of the first night. Norwegian mountain weather in late July is genuinely variable — reports describe conditions ranging from tall snow banks on both sides of the mountain road to 20 degrees warmth on the same mountain in different years.
