Mastodon Rumbler
Hillsborough, Canada • 20 Jun 2026
Mastodon Rumbler - Second Edition
Mastodon Rumbler is a trail race taking place on June 20, 2026, at Whiterocks Hills in Hillsborough, New Brunswick (297 Taylor Ln). This is the event's second edition, held on the trails around White Rocks Recreation Park.
The course follows winding trails with changes in elevation. Organizers note the area has layers of history: prehistoric mastodons once roamed the land and later mining operations altered the hills that runners will encounter.
Multiple distances are offered:
- 10 ish - First of two loops, covers most outer park trails with a few small hills.
- 20 ish - Two distinct loops; the added loop is described as the most scenic.
A portion of proceeds will support the development of a local Hillsborough community playground. Another portion will be donated to Codiac Cycle Trails, which maintains and develops the White Rocks Recreation Park.
The available information focuses on course character, distance options, community fundraising purposes, and the event location. Visit the organization's website for the most recent information.
