Race planning

Plan Bislett 24-Hour Indoor Challenge

Use the listed edition as your starting point. Each tool keeps imported race facts separate from the targets and assumptions you choose.

Edition notes: Sold out. Registration for the 2026 lottery ran from May 1 to May 4 and the draw was on May 5: 683 runners applied for 150 places, and the field is capped at 165. The only way in now is to buy a place from an entrant through the organizer’s resale procedure, open until November 15 with a NOK 400 transfer fee. The organizer lists an IAU Bronze Label, but the IAU calendar entry for 2026 shows no label. The 2026 participant information had not been published on October 20, so the race-day rules below come from the 2025 edition.

Listed edition

Nov 21, 2026 – Nov 22, 2026

Format

24-Hour

Distance

24 hr (official 100-mile split)

Local start time

10:00 AM Saturday, November 21. In 2025 the doors opened at 7:30 AM and bib collection started at 8:00 AM.

Duration / cutoff

24 hours, ending at 10:00 AM Sunday, November 22. At the end signal runners stop where they are and wait until their partial lap has been measured, which can take 10–15 minutes.

Crew and pacers

No pacing. Only runners and officials may be on the track, and supporters may not run alongside or give support outside the support zone; repeated violations lead to disqualification. Supporters may not take food or drink from the organizer’s service station.

Drop bags

No drop bags. Runners and their supporters share tables in the support zone on the sprint straight opposite the entrance, and may set up their own camping table behind them. There is no room for personal supplies on the entrance side.
