2189 - 2nd Annual Naticook Challenge 5k OCR

Join Merrimack Parks and Recreation for the second annual Naticook Challenge Obstacle Course Race.

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.

This course is perfect for both those who have never run an Obstacle Course Race before, and also veterans of OCR who are looking to get out and have some fun.

Start wave times are assigned based on age group and are as follows:
Ages 40+: 8:00am Start time
Ages 19- 39: 9:00am Start time
Ages 8 - 18/Family: 10:00am Start time

Please arrive before your start hour to check in and get your race bib. For any start time conflicts (or people that want to run together that are in different age groups) please call Program Coordinator James Golisano at 603-420-1664.

Participants will receive an official Naticook Challenge Runners T-Shirt and a participant completion medal.

Prizes will be awarded in the following categories:
Ages 8 - 18: Male First place prize
Ages 8 - 18: Female First place prize
Ages 19- 39: Male First place prize
Ages 19- 39: Female First place prize
