Registration fees increase on July 4th–sign up now!

Welcome to the inaugural Mahoosuc Ridge to The River Challenge! This years’ trail running race will reward 10k’ers with farms, paved and logging roads, beautiful views, forests and trails, while an additional 8 mountain peaks, stunning vistas, and the soon-to-be-infamous (and possibly despised) Spruce Cliffs await the half-marathoners. Oh, and then there’s the Maine Brew Fest and food trucks at Sunday River…more about that later:)

We’ll update with details as soon as the trails are free of snow and mud so we can solidify the courses. Plan on a moderately difficult 10km course, suitable for newbie racers, hikers, and seasoned runners; and a doozy of an adventure for the half-marathon.

True to it’s backcountry nature, this event offers approximate distances, and may differ year-to-year. This is not your typical 10k or 13.1….put aside your plans for a PR and gear up for your new yearly challenge.


  • Start/finish: Race start is at Mahoosuc Land Trust’s Valentine Farm at 162 North Road in Bethel. Race finish is at South Ridge at Sunday River. All races start at 10am; untimed hikers/walkers start at 10:05am.
  • Parking: Ample parking is available at Sunday River, with free shuttles to Valentine Farm from 7am-9:45am. Please put any belongings you need to leave at Valentine Farm in a bag with your name. We will shuttle all bags to Sunday River after the start of the race.
  • Registration and bib pick-up: 7:30am-9:30am at Valentine Farm. T-shirts will be available for sale until they run out!
  • Facilities: Port-a-pots will be available at Valentine Farm and Sunday River.


  • 10k(ish)/Hiking/Untimed: A mix of logging roads, trails, and ski slopes with a paved road start. Perfect for all ability levels!
  • Half-marathon (or somewhere thereabouts): A mix of logging roads, trails, ski slopes, steep & rocky hills, and several mountain peaks with a paved road start. Prepare thyself.

10k(ish)/Hiking/Untimed, and Half-marathon (or somewhere thereabouts): After the paved road teaser of about 1.4 miles, you will enter the woods and encounter rough, rocky, rolling double track on old logging roads and snowmobile trails, along with single track on trails and deer paths. Just when you start thinking, “This ain’t so bad,” you begin a long, arduous ascent through the Bethel Community Forest to a height of land where you begin a descent to the Sunday River Ski Resort and the Moonstruck Trail. This is where you 10k runners begin your traverse across trails, ski slopes and dirt access roads to the finish at South Ridge Ski Resort at Sunday River. But for you half marathoners, it’s just getting interesting. Now you get to scramble up the course’s biggest climb, the 1000 vertical foot single track known as “After Shock” and over several (exact number to-be-determined) of Sunday River’s summits (including the infamous, short but bitter Spruce Cliffs and the 3000’ + Jordan Peak), loping along a rocky mountain ridge with spectacular views – if it’s clear, that is. Along the entire course, we have strategically filled the trails with rocks, roots, muddy ditches, boulders, and steep ledges. (Truthfully, we found all those goodies already in place and decided to leave them so you can enjoy them as much as we did while laying out the course. We left the bears in the mountains too, but most likely your heavy breathing will alert them from a mile away and you’ll never get to see any). After traversing the pointless ups and downs along the ridge you will descend on gnarly ski trails but also a few merciful stretches of packed gravel access roads. A cold beer from one of Maine’s craft brewers will be waiting for you. If, when you finish, you find the course didn’t suck enough, please give us specific feedback so we can rectify that for next year.


Locally-made prizes will be awarded to the first two male and female finishers in the following categories:

  • 17 and under
  • Open (18-39)
  • Masters (40-49)
  • Seniors (50+)
  • Team (mens, womens, and mixed; minimum 3 people per team)
  • Additional awards will go to the overall mens and womens first-place finishers

When three Bethel-area non-profits got together, something big happened. Well, more than one thing, actually. Mahoosuc Land Trust aims to conserve land to benefit the natural areas and communities in the Mahoosuc Region; Mahoosuc Pathways strives to connect communities through trails; and The River Fund focuses on creating a bright future for youth through education and recreation. And when they realized they could do more good together, the Ridge to The River was created.

This collaboration not only brings an incredible new event to the area, but it also supports the missions of these organizations by highlighting the value of our lands, recreational opportunities, and community & youth development. Thank you for being a part of this exciting event and supporting our collaboration!
