Transfer Credit Policy

***2020 Credit Deadlines Updated due to COVID-19 and Race Postponement

Registered runners may also switch between races. Runners in the 25 mile race can pay the additional registration fee to upgrade to the 50 mile race. There is no fee for 50 mile runners to drop to the 25 mile race.

Runners who drop to the 25 on race day will not be eligible for 25 mile overall or age group awards but will receive a finish time and finisher award.

50 milers who request to drop to the 25 mile race by packet pickup will be officially entered into the 25 mile race and will be eligible for 25 mile awards. Otherwise all 50 mile entrants will be expected to start with the 50 mile race in their designated wave.
