Glen Iris 5K & 10K Trail Run

Castile, NY

5K & 10K Trail Run/Walk
Letchworth State Park
The "Grand Canyon" of the East

Please join us on Sunday September 8, 2024 for the Glen Iris 5K & 10K Trail Run/WalkThis event will take place entirely inside Letchworth State Park that features breathtaking views Genesee River Gorge known as the Grand Canyon of the East! 

In 2016 the park was voted as the #1 New York State Park and in 2017 it was voted the #1 attraction in New York State! Participants are encouraged to visit the official park website learn about all the great things happening at Letchworth.

START TIME 9AM: Both the 5K Trail Run and 10K Trail Run will take place entirely on park woodland trails and will both start and finish near the Trout Pond. Runners will enjoy CHALLENGING trails that feature breathtaking views of the woodland forest, wildlife, creeks & streams, bridges, and more. After last year's race it was decided that this run is so tough that EVERYONE deserves an fully custom keepsake finisher medal. I'm excited to announce that we have already placed the order and these beautiful keepsake medals will be presented to all runners at the finish line on race day!  Interactive trail maps for both distances are shown below.
