Come and join Merrimack Parks & Recreation for the 3rd Annual  Naticook Challenge 5K Obstacle Course Race that is fun and challenging  race to test your ability.

If you are new to this, you may be  asking yourself, what is an obstacle course race? It is a trail based  race that takes place within Wasserman Park as well as on the  Conservation Trails that border the Park and that involves challenges  for the other parts of your body (crawling, climbing, or hanging for  examples).

The course is a 5k distance and includes 8 or more  beginner to intermediate level obstacles. There are obstacle bypass  exercises  available if unable to complete an obstacle.  Racers will not  encounter any water obstacles or crossings but will be on a mix of  trails and varied terrain with rapid elevation change as they complete a  total of 5  kilometers.  Don’t let this scare you away, our obstacles  are designed with beginners in mind and are achievable by most people,  even kids.

Sign up and earn your Naticook Challenge Shirt, medal and bragging rights.
