Blue Hills Adventure Race
About this race
The Blue Hills Adventure Race brings traditional adventure racing back to Massachusetts for the first time in well over a decade. Join us for an exciting one-day adventure race, combining mountain biking, foot travel, paddling, and map-and-compass navigation as we explore the lush Connecticut River Valley in this inaugural edition.
Some sources note that Massachusetts derives its name from the Wopanaak word muswachasut, referencing the state's Blue Hills, and while the first edition of the Blue Hills AR will explore land far from the state's place name, over the course of fifteen hours, competitors will become well-acquainted with the Bay State's hills, forests, and waterways.
For veteran adventure racers, the Blue Hills AR offers everything you've come to expect from a Rootstock event: challenging navigation, rewarding checkpoints, strategy and route choice, and a fun and welcoming community. It is a course ready for top competitors, and it is accessible to newer racers excited to dive into AR.
And for the newcomers: while the Blue Hills AR is not a beginner-FOCUSED race, we have designed the course with all calibers of teams in mind, using a "modified rogaine" format; all teams must complete a designated mandatory route which requires less navigational ability and is short enough that all teams should have time to reach the finish line with adequate baseline fitness. For more experienced teams there will be additional, optional checkpoints to challenge even the fastest teams and best navigators.

A NOTE ON BOATS: The Blue Hills AR is BYOB: bring your own boats. We recommend canoes or touring-style kayaks for this event, as you will be paddling on flowing water. Packrafts will suffice, though they are obviously slower. You will drop your boats at a "boat drop," which we will announce closer to the event. For any teams who are not able to source boats but still want to participate, we will provide an alternate route that allows you to bypass the paddling stage(s) on bike. Because the official full course design requires you to paddle, prizes are reserved for top teams completing all disciplines of the event, so you will be ranked behind any teams that do complete the paddle.
