Course and logistics
Distances:
- 5K (two loops of the lollipop course)
- 1.6 miles (single loop fun run option)
The course is a 1.60-mile lollipop loop repeated twice to make the 5K. Except for a short single-track connector under 0.20 miles, the route is a wide gravel/dirt trail around Scarlet Oak Pond. The loop is described as very flat and not technical; road shoes are acceptable and trekking poles are allowed. The course will be marked with bright ribbons and large red directional arrows. Participants should park in the Reservation parking lot; restrooms are available there. The organizer provides a first aid kit and an AED, plus private changing tents. Refunds are not offered; a deferral policy is available under specified conditions. Visit the organization's website for the most recent information.
