Race planning
Plan Arrowhead 135
Use the listed edition as your starting point. Each tool keeps imported race facts separate from the targets and assumptions you choose.
Edition notes: The 23rd Arrowhead runs January 25–27, 2027. Applications opened on UltraSignup at 8:00 AM Central on September 1, 2026, and on October 20 UltraSignup showed registration closed since October 10, 2026; the entrant list is hidden. The organizer's rules page is headed 'for 2027' but still gives the previous year's gear-check and start dates (Saturday January 24, Sunday January 25, Monday January 26), so confirm the 2027 race-week times in the racer information. UltraSignup lists the start as 7:00 AM Monday, January 25, 2027. The 2027 Trackleaders tracking page had not been posted on October 20.

- Local start time
- 7:00 AM Monday, January 25, 2027, at Kerry Park Arena (UltraSignup). In 2026 the official results show bikes starting at 7:00 AM, skiers at 7:02 AM and foot racers at 7:04 AM.
- Duration / cutoff
- 60 hours: the finish at Fortune Bay closes at 7:00 PM Wednesday. Racers must leave Gateway (mile 35) by 9:00 PM Monday, MelGeorge's (mile 70) by 1:00 PM Tuesday and the Embark checkpoint (about mile 110) by 10:00 AM Wednesday. A missed cutoff ends the race, and anyone who keeps going after missing one is banned from future Arrowheads.
- Crew and pacers
- No crews, pacers or outside help of any kind, including at MelGeorge's. Spectators are welcome but may not assist, and no snowmobiles may follow, meet or break trail for a racer. Racers may help each other. Taking a ride or getting into a warm vehicle means disqualification. Unsupported racers check in at checkpoints but take no food, water or warming time there.
- Drop bags
- One see-through drop bag of up to 10 lb for MelGeorge's, holding food and drink only. New for 2027, it is inspected at gear check. It is stored on an unheated porch and is not returned. A separate small bag with a change of disposable clothes goes to the Fortune Bay finish. Both are due at gear check by 2:30 PM Sunday.
