2022 RMR Notice

The 6th Annual Rose Mountain Rumble benefit bike ride is scheduled for Saturday, August 27th, 2022.  Registration opens June 1.  The RMR is a non-timed “gravel ride” that tours the scenic dirt roads of Lyndeborough and surrounding towns. We welcome riders of every ability and offer a variety of route options from a 20-miler for casual riders to a full 100K course to challenge the most competitive gravel grinder. All routes are marked, and cue sheets are provided. The ride begins and ends at Lyndeborough Center Hall, with a delicious post-ride lunch provided by the Wilton-Lyndeborough Women’s Club. Net proceeds benefit the Piscataquog Land Conservancy.

The Rose Mountain Rumble

Gravel.  Dirt.  Gravel Grinder.  Call it what you want.  Jest at what you may refer to as “that’s just a road ride”.  One thing is for certain: The Rose Mountain Rumble is one heck of a ride!  We’ve unlocked all the best-kept secrets of Southern New Hampshire’s vast network of well-maintained dirt roads and selected courses to give novice riders a taste of adventure while putting the hardiest of seasoned veteran cyclists’ skills to the test.  The RMR’s courses twist and wind their way through old dirt roadbeds long-forgotten linking quaint New England town centers akin to a snapshot from our nation’s scrapbook.  Riders will enjoy peace and quiet from the bustle they call home.   Trace your way through historic, rock-wall lined, narrow roads that lead to scenic overlooks.  You haven’t truly ridden until you’ve ridden the Rose Mountain Rumble.

The Rose Mountain Rumble’s 100k course option takes you out of town and into the sticks.  If the 40 miler is no joke, the RMR 100k takes things up a few notches.  We’re bringin’ the hammer with the nails with this one!  A minimum of 32mm tires are recommended. The course begins at the Historic Lyndeborough Old Town Hall alongside the 40 and 20-mile course, which quickly enters gravel.  Leave the at kids home.  Pack an extra set of undies and make sure you have mom’s phone number just in case. The 100k course is equally a fast-paced ripper chocked full of scenic dirt roads, good tree cover, scenic overlooks, technical descents and climbs but takes you into some rough territory.  Be prepared.  You don’t want to miss this one!

All proceeds from the RMR benefit the Piscataquog Land Conservancy (PLC), a non-profit land conservation organization working to conserve the natural resources and scenic beauty of the Piscataquog, Souhegan and Nashua River valleys of southern New Hampshire.   The inaugural RMR was held in August 2015 as part of PLC’s successful campaign to protect 189 acres surrounding the summit of Rose Mountain in Lyndeborough, NH. The land was protected, the ride was great and the name stuck!


A special thank you to all of our event sponsors.  We hope to see you and more of your friends again for the Rose Mountain Rumble!
