Weather: MammothMarch remains on schedule, rain or shine. While it’s nearly impossible to predict the weather more than 24 hours ahead of time, we are in constant exchange with the Park and all entities involved. There is - always - a chance of inclement weather during our events, simply because it's a full-day outdoor activity.

We have several options in case of inclement weather (e.g. postponing the start if we experience severe weather in the morning hours or cutting short later on) with the last resort being an event cancellation. Please monitor your email inbox and our social media in particular for any short-term adjustments/changes.

Saturday, August 12 | Letchworth State Park

MammothMarch is back in Upstate New York!

We are thrilled to have secured Letchworth State Park, renowned as the “Grand Canyon of the East”, for our second NY edition. Hike 20 miles in 8 hours and conquer one of the most scenic areas in the Eastern US.

Our single-circuit, 20-mile hiking route leads along the Genesee River, through lush forests, and includes spectacular waterfall views.

Several times voted as “Best Park in the United States”, Letchworth is located just an hour east of Buffalo/south of Rochester and is one of the most scenically magnificent MammothMarches in our 2023 calendar.

Mastering our challenge, you will be exhausted, but proud and happy... as well as part of our amazing community of nature-lovers, hikers and MammothMarch addicts!
