Mastodon Rumbler : Second edition
Mastodon Rumbler is a trail race scheduled for June 20, 2026, in Whiterocks Hills, Hillsborough, New Brunswick. The event takes place on trails within White Rocks Recreation Park, a landscape described as shaped by prehistoric mastodon activity and past mining operations.
Part of the proceeds will support development of a Hillsborough community playground. Another portion will be donated to Codiac Cycle Trails for maintenance and development of White Rocks Recreation Park.
The course offers two distance options:
- 10 ish: a single loop around the outer part of the park, with a few small hills.
- 20 ish: two distinct loops; the first matches the 10 ish route, the second is a different, more scenic loop.
Displayed prices include mandatory charges. The listed amounts are CA$78.76 for the 10 ish option and CA$100.60 for the 20 ish option. Base prices of CA$65 and CA$85 are shown for the registration period from Jan 30 to Jun 19. Visit the organization's website for the most recent information.
