The two aid stations (one on the course and start/finish) are staffed by fellow runners, friends and family members. Please make every effort to thank them for their time and efforts!

The first aid station is 6ish miles from start and the second aid station is just before the point where the 10-milers head to the finish and where the 20-milers head out on loop two.

We will have portable toilets available at the start/finish line and aid stations. We ask that you use these facilities and keep the trails clean. Leave no trace.

Pacers and Crew
Pacers are NOT allowed. Runners can have a crew but may only administer aid at the aid stations.

Should you need to drop from the race, remove your bib and give directly to an aid station crew captain.

If you leave the course and fail to notify race officials, you will be asked not to participate in future St. Croix Running Company events.
