READY TO RUN

From race morning to after the finish.

Your start time, fuel and bag drop.
Know them ahead and the run feels easier.

Caseville in April — average temperature 5°C, so the cold is a major factor.

Spend as much time as possible indoors before the start so you do not get chilled, and bring gloves, a beanie, and a neck warmer for safety.

Public transit does not reach the race venue.

A personal or rental car is the only realistic way to get there.

Registration is handled through the RunSignup platform.

Ultras are decided by fueling and foot care, not speed.

Break in your shoes and socks thoroughly before race day, and if there are sections at night, bring spare batteries for your headlamp.

The 06:27 start is early.

Counting backward from your wake-up time, breakfast, and travel, staying near start line the night before will be more convenient.

Registration is open until 22 April 2027.

Times are local to Caseville. Check the latest official information before the race.
