The Great 41-Mile Challenge 2026

These walks are a continuation of our very popular 26 Mile Challenge and are designed for those who want to earn their 41 Mile Patch & Certificate. Over the course of 3 walks, we will cover the 15 miles of the Old Croton Aqueduct within the borders of New York City, starting at the northern end of Van Cortlandt Park and ending at 42nd Street and Fifth Avenue. If you have already completed the 26 miles of the OCA trail in Westchester, you will be eligible to receive a 41 Mile Patch & Certificate when you complete these 3 walks.

Walks will be held on the following Wednesdays: 9/23, 10/7 and 10/21.
