CHALLENGE THE SHIELD

MULTI-SPORT ADVENTURE RACE

Parry Sound, ON



SEPTEMBER 7, 2025

OVERVIEW
The Challenge the Shield Multi-Sport Adventure Race is an awe-inspiring wilderness endurance challenge on the rugged Canadian Shield. Teams of two have up to 6 hours to tackle as many of the ~30 checkpoint or segment challenges amongst the iconic windswept pines, pristine lakes and granite rock barrens as they choose. The "choose-your-own-adventure" points-based course design is both beginner-friendly and an epic challenge of strategy and adventure for even the most experienced teams.  Shred some wicked granite slab MTB trails. Navigate to as many of the beginner, intermediate, or advanced checkpoints as possible. Paddle and portage to a backcountry lake. Try a swim run at the end of the race. You decide the adventure!
Challenge your friends.  Challenge yourself. Challenge the Shield!

HOST SITE
Nine Mile Lake Beach (near the Georgian Nordic Outdoor Activity Centre ~10km NE of Parry Sound, ON)

RACE FORMAT
6-hour time limit.  A total of 2,500 points are up for grabs.  The race begins with a three-part mandatory segment challenge (500 points); a marked-route ~ 3.5 km run/trek, followed by an ~ 2 km paddle, and then an ~ 7 km bike. After completing the segment challenge, there are trek, paddle and bike checkpoint challenge sections (up to 625 points each) which can be taken in any order. Each checkpoint challenge section has 9 checkpoints of varying difficulty and points value (you can choose as many as you like in each discipline). The more checkpoints you get the more points you score. Total checkpoint challenge section distances are 10-12 km for the trek, 10-12 km for the paddle, and 20-25 km for the bike. The race ends with an optional 125 point marked-route swim-run segment challenge.  A penalty of 100 points for every minute (or part) over the 6-hour time limit will be deducted.
