2021 RMR Notice

Save the Date! Rose Mountain Rumble returns Aug. 28th after being cancelled in 2020 due to the coronavirus pandemic, the 6th Annual Rose Mountain Rumble benefit bike ride is provisionally scheduled for Saturday, August 28th, 2021. We are giving ourselves a few more weeks to watch the evolving public health guidance but expect to open registration by early June. 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

August 28, 2021 · Cycling Dirt Roads to Benefit Conservation · 8am Sign in / 9am Start


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 road beds long forgotten linking quaint New England town centers akin to a snapshot from our nations scrap book.  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 Cause


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 our 2019 RMR event sponsors: Airmar Technology Corporation of Milford, NH!

We hope to see you and more of your friends again for the Rose Mountain Rumble!
