Relay Race Details (Start Time 7:00AM):
Relay teams consist of 4 people sharing one assigned bib with an adjustable belt that can be exchanged between team members. Each racer signs up individually and can choose one of the following options:
-
No Team (the race organizers will assign you to a team)
-
Join an Existing Team
-
Create a New Team
All teams start together with the 1st runner of each team running the red loop at the same time. Once completed, the 1st runner passes the bib to the 2nd team member who will complete the green loop. Once completed, the 2nd team member passes the bib to the 3rd team member who will complete the black loop. Once completed, the 3rd team member passes on the bib to the 4th team member who will run the red loop, followed by the 1st team member who will run the green loop, followed by the 2nd team member who will run the black loop and so on, until all 4 team members each have completed all three loops. Race timing will provide results for entire teams as well as individual times (splits) on each separate trail loop.
All three loops combined are exactly 13.1 miles, the distance of a half marathon. The relay race is expected to take 10-12 hours. Due to the rugged terrain which includes steep downhills, headlamps are mandatory for any runners after 8:00PM.
