New this year: FULL MARATHON category!!

Welcome to the second annual Mahoosuc Ridge to The River Challenge! Please note that the course, course profiles, and course descriptions are subject to change. Info will be updated regularly. Here’s what we know: you’ll see farms, paved and logging roads, beautiful views, forests and trails; and for you half-marathoners you’ll get an additional 8 mountain peaks, stunning vistas, and the infamous (and sometimes despised) Spruce Cliffs and Aftershock. We have something very special for the marathoners: another 3,200 feet of elevation. 

True to its backcountry nature, this event offers approximate distances and may differ year-to-year. This is not your typical 10k or 13.1…or 26.2. Put aside your plans for a PR and gear up for your new yearly challenge.

2019 Race Results:


10k(ish)/Hiking/Untimed: ( Click to Open)

Note: course subject to change.) A mix of logging roads, trails, and ski slopes with a paved road start. Perfect for all ability levels! 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 rocky/rooty foot-snaggers. 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.


Half-marathon (or somewhere thereabouts): ( Click to Open)

(Note: course subject to change.) A mix of logging roads, trails, ski slopes, steep & rocky hills, and several mountain peaks with a paved road start. Prepare thyself. 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 Sunday River summits (hitting the infamous 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.


Full Marathon (roughly): ( Click to Open)

(Note: course subject to change): See above description, then double it. Think 7,000+ of vert. Full marathon: We’re planning to have the start at Sunday River and backtrack to the start of the other races…then it’s up and over and back down to SR. Ouch. We’ll be scouting out trails in the Community Forest so that you won’t have to do any road running. There’s the potential of this adding elevation, so plan for it!


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.

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!
