Mahoosuc Ridge to The River Challenge

Welcome to the third annual R2R! We chose Sunday River Resort in order to maximize climbing feet and incredible views. It's a good balance: while your heart is pounding and you are cursing our choice of course, the beauty around you will keep you moving forward. 

We pulled off a great event in 2020, and we know we can do it again in 2021. Know that the event will be designed to keep our staff, volunteers, partners, and you--the runners--safe, while still offering an incredibly challenging course. 

Here's what we do know: all runners will see logging roads, beautiful views, forests, rough trails, stunning mountain peaks, and the infamous Aftershock. Half marathoners will get an additional 5 mountain peaks with incredible vistas and a few thousand (give or take) feet of elevation. 

And we have something very special for you marathoners: you get to run the course twice. You're welcome. 

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.
