The Harrimeter is a 45-mile route that roughly follows the perimeter of Harriman State Park in New York.

This route completes the entire Cross Timbers main trail including the newest edition of 11 miles. Start at Cedar Bayou Marina, then head east to Juniper Point and then back to the start (7ish miles) to stock up on water at your car. Stop at Rock Creek Marina shop to buy water at mile 23ish and continue to turn around at mile 28ish miles. You will be back at the shop to refill on water again at mile 33ish before you head to the finish. The coolest part about this route is all the signage along the way with clever saying.
