The published layout
The FAQ describes a usual 10.55km loop repeated four times, with aid approximately every 5km. The full and Frozen Continent Half Marathon take place in the Union Glacier area.
Terrain
Grooming generally creates a firmer surface, but soft snow, loose patches and ice may still appear. Trail shoes are the organizer’s suggested footwear. Running on snow can take longer and require more effort than road running.
Use the briefing
Follow the marked route and the final course briefing. The published cutoffs are ten hours for the full marathon and six for the half, with the race director retaining authority over race operations.
Your final participant instructions and approved event terms take priority. Check your dashboard for organizer updates.
