The Course
A mountain ultra above the Arctic Circle in northern Norway, run under 24 hours of continuous daylight during the midnight sun. The course follows ridgeline trails above Tromsø — the "Gateway to the Arctic" — with views of the Norwegian Sea, snow-capped peaks, and fjords far below. The terrain is alpine tundra, boulder fields, and steep snow patches that persist well into July. Running at midnight with the sun on the horizon creates a surreal, timeless quality that no other ultra replicates.

Lore & Trivia
Tromsø — 350km north of the Arctic Circle — is the largest city in northern Norway and the gateway to the Arctic. The midnight sun marathon and ultra series runs under 24 hours of continuous daylight in late June, when the sun circles the horizon without setting. The psychological effect is extraordinary: running at 2am in bright sunlight, your body's circadian rhythm completely confused, surrounded by fjords and snow-capped peaks in endless golden light. It's the most surreal race experience in European ultrarunning.
- ▸ At 69°N, the sun doesn't set for two months in summer.
