Welcome to the Lost Cat

The Lost Cat is a scenic and challenging road-to-trail race that takes you through hardwoord forests and past historic marble quarries on Dorset's Mount Aeolus. 

A portion of the proceeds will be donated to the Second Chance Animal Center. The Lost Cat is part of the Dorset Running Festival, a weekend of races! 

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 from the height of Vermont's marble boom. The 50k consists of roughly 50% trail (about half and half singletrack and doubletrack/jeep trail) and 50% road (10% pavement, 40% packed dirt/gravel). Don't be fooled by the labels, the singletrack is very flowy and runable, whereas sections of the jeep roads are some of the most technical trail you can find. 

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. 

This is NOT a flat race! The half marathon has approximately 2,400' of climbing and the 50k has approximately 4,500'. 


If you don't like dirt roads, you won't like this course. In the style of classic races like the JFK 50 and the Vermont 100, the Lost Cat is a great way to showcase your speed and practice tough transitions while hitting a wide variety of terrain. This is not the most technical course, though some sections are technical enough to make you regret saying that. Depending on the year and how recently some of the jeep roads have washed out, some sections can look more like rocky technical trail or like smooth runable road. 2019's race featured a rock pile the size of a small house near the finish of the course. Be prepared for lots of changing gears and unbelievably cruisy descents. Road shoes and trail shoes are both a bad choice.


Note that the 50k has the most trail of any of the distances. If you drop down to the marathon you'll be missing out on one of the most scenic sections of the course, 5 miles of trail straight up Mount Aeolus. 

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; all distances will cover the highway stretch. 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!! 

The CUTOFF time for all distances will be 4 PM. This gives half marathoners 7 hours, making it a great event for walkers!


The Lost Cat will be photographed by renowned sports photographer Joe Viger. All participants will take home FREE web-sized downloads of their photos, courtesy of Nor'east Trail Runs! Higher resolution prints and downloads are also available - support your amazing photographers! Last year, two Lost Cat runners wound up on the cover of the American Trail Running Association (ATRA) page when one of Joe's photos was selected to represent USA trail running around the world!

Aid Stations

There will be fully stocked aid stations every 3-7 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. 

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.

Swag & Awards

All runners will receive a tech shirt. Finishers get a custom dog tag medal and a finisher's pint glass! (*Must register by August 1 to guarantee a shirt)

All finishers will receive a custom dog tag and Official Finisher pint glass. 50k finishers take home a unique trophy that can't be had anywhere else, we promise. You'll have to find out what it is by finishing... Custom, locally made awards for top three male and female at each distance! 

There will be a raffle to benefit the Second Chance Animal Shelter with great local prizes courtesy of our awesome sponsors on Sunday, 8/25 following the Dorset Hollow Road Race 5k & 10k! Tickets will be available to purchase at the Lost Cat. 100% of the proceeds go to Second Chance!
