The RMR 100k

100k Course Description


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 along side the 40 and 20 mile course, quickly enters gravel at Dutton Road, follows the 20 and 40 mile courses but takes an abrupt turn in Francestown, NH and starts up a climb that is not for the faint of heart.  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.  There’s some nasty sections.  Nothing too scary but certainly not a walk in the park!  This is a super fun challenging course.  It won’t kill you but like the 40, certainly puts your mettle to the test.  The course boasts well over 80% gravel roads.  This one is where tall tales begin and adventures are put to memory.

  • 100k Approximate Elevation Gain: 1879m / 6165′
  • Water stops are provided along the course, but be sure to bring sufficient water and food to be self sufficient.
  • Bring a spare or two and be sure not to forget your tool kit.
  • It is advised you run a minimum of 32mm tires.  40mm’s are even better.
  • Lunch is provided at course’s end.
  • There is a 10 mile bonus lap to bring the total mileage to ~74 miles with one heck of a climb at the very end for those who feel they didn’t get enough climbing in…

The RMR 50 Miler: NEW Route for 2020!

Course Description


NEW FOR THE 2020 RMR: The Rose Mountain Rumble’s 50 miler gets it’s very own route!  If the 40 miler is just too short but the 100k is a bit too long, then the 50’s gotta be “just so”.  This course will not disappoint.  Enjoy the finer points of the 20 and 40 miler but you’re in for a real treat as you wave goodbye to those riders and you follow the 100k riders up Bunker Hill Road.  This quickly turns to dirt and you part ways with the 100k as you ride deep into Francestown’s off the beaten track roads and deep into the thick of good old fashioned New England gravel.  Finish right back where you started as the aroma of lunch lures you home!

  • 50 Miler Approximate Elevation Gain: 1432m / 4698′
  • Water stops are provided along the course, but be sure to bring sufficient water and food to be self-sufficient.
  • Bring a spare or two and be sure don’t forget your tool kit.
  • Lunch is provided at course’s end.
