"Open 4" is a fun navigation format where participants have up to 4 hours to score as many points as possible by finding control points in the woods on foot and on mountain bike. Yes, a portion of the course is designed exclusively for bikes! You do not have to attempt the bike portion, but it will be fun (and challenging). The course is designed so that both the novice and the expert navigator will have a good time in the woods. We'll have snacks available at headquarters, so you can always come back to regroup, then head back out again. Novice racers or families with younger children are welcome to adjust the time down to whatever meets your needs. We will have our coveted "woodal" awards for the top three teams.
