October 19, 2019
11:00am - 2:00pm

ChesLen Preserve is the largest privately owned nature preserve open to the public in Chester County. Miles of marked hiking trails lead visitors through shady woodlands, flower-filled meadows, fields of corn and soybeans, and stream valleys.

Visitors can also explore Ollie Owl’s NaturePlayGround, where young explorers can climb logs, build stick tee-pees, hunt for bugs, explore small streams, and get a little dirty, tired, and inspired. Free play is encouraged and is a great way for kids to gain an appreciation for nature.

Please note, if arriving via Route 842, Cannery Road will be closed to vehicular traffic beginning at 10:45 am, and will remain closed until all runners have finished. Anyone arriving after 10:45 am will be redirected to Route 162. Vehicles will be permitted to enter Cannery Rd from Rte. 162 and travel up as far as the race site at the Lenfest Center.
