The Naticook Challenge 5K Obstacle Course Race returns to Wasserman Park on Saturday October 12th for it’s fifth year. Come and join Merrimack Parks & Recreation for this Annual 5K Race that is both fun and challenging to test your abilities. 

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. 

The first 125 registered participants will receive an official Naticook Challenge  Runners T-Shirt. All registered participants will also earn a completion medal. 

Cost of this year’s race is $35 ppFor complete details or to register, visit us online at: https://merrimackparksandrec.org/naticook-challenge-5k
