Course Description

The course consists of 3 loops around St. Mary's River Park.   Runners have the option of completing one loop (17K), two loops (34K), or three loops for the full 50K distance.  Distances are approximate and not officially certified.  Due to erosion, plate tectonics, and global warming, the course may not measure exactly 50K.  

The trails are singletrack and mostly runnable with some technical sections with tree roots.  There are some minor hills, but no significant elevation change. The surface of the trail is mostly packed dirt, but there are a few sandy sections and a half mile portion of crushed stone.  Water crossings have bridges, but weather conditions may provide additional challenges on the trail like snow, water, mud - oh my!  The course will be clearly marked with streamers and there will also be signs and markers to keep runners on course.  

Due to a significant portion of single track trail, NO pets and NO strollers.  

Time Limit:  8 hours

50K runners who do not start the third loop by 5.5 hours will be asked to drop down to the 34K option.  To stay on pace, runners will be expected to reach Aid Station #2 (~40K) by 6.75 hours.


This event is manually (not chip) timed. 

  • All runners will be tracked through each aid station. 
  • Your race bib must be worn on the front of your body outside of your clothing so that it is visible and can be recorded by a volunteer for each pass through

Aid Stations

There are two aid stations on the loop – one at the start and one at the mid-point, approximately 5 miles apart.  Due to the distance between stations, it is highly recommended that you run with your own hydration.  

Stations will be stocked with water, sports drink, soda, gels, baked goods, sweet and salty snacks, soups, and more to help fuel your run!  Race nutrition sponsored by GU Energy who will be providing GU Energy Gels and Hydration Drink Mix!!  Both stations will have port-a-potties available.

Gear check is your car.  The start/finish is just steps from the parking lot and you be able to access your car at the end of each loop.
