The Lost Cat 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)

Starting down low at Town Hall in East Dorset, you'll get a rolling prelude to the climbs ahead. Historic orchards and stands of sugar maple line this part of the course. The course then transitions to steeper class 4 roads and trails on Mount Aeolus after a beautiful 5k singletrack section through old pine plantations 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. You will also cross an active set of railroad tracks... 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!
