This rugged course on Dorset's Mount Aeolus takes you through hardwood forests and past historic marble quarries. A portion of the proceeds will be donated to the Second Chance Animal Shelter. 

Stick around after the race and fuel up with some local treats and offerings from our sponsors!

This course offers steep climbs, varied terrain, and scenic descents. Incredible valley views and historic buildings. A mix of singletrack, ATV roads, packed dirt, and pavement.

The race will start at Town Hall in East Dorset with a rolling prelude to the climbs ahead. Historic orchards and stands of sugar maple line this part of the course. You will then transition to steeper class 4 roads and trails on Mount Aeolus after a 5k rolling singletrack section above Emerald Lake. All distances are a single loop-type format, and will end back in town where they started.  

Due to the land ownership considerations, there will not be a course map available before the race. Rough outlines and Aid Station locations will be available, along with crew/spectator access directions. The course will be very well-marked.

There is a ~2 mile highway section positioned several miles into the course. There is ample shoulder and good visibility, however it is the runner's responsibility to ensure they are safe on the road. This includes bright or reflective clothing, etc. There will be volunteers, flagging, and marking on the road sections of the course, but traffic will not be stopped on this segment. There is also one railroad crossing you will do twice! While it's unlikely any trains will be present, be prepared to wait a couple of minutes. 

Be prepared for mountain weather and changing conditions. As we say in Vermont, if you don't like the weather wait 5 minutes!!

Aid stations

There will be fully stocked aid stations every 3-6 miles. Aid stations will feature Hammer Heed electrolyte drinks, Hammer gels, and Hammer Endurolyte salt tabs. Expect all the traditional sweet and salty aid station foods plus MAPLE SYRUP SHOTS available on-course. Seriously. 

Bring a bottle or pack for water! It may be hot and humid and the next aid station might feel a lot further than it is!

There will be one drop bag location near the midpoint of the 50k with crew access. Drop bags/crew for marathon and 50k runners only.
