11th Annual Flanders Field & Forest 5K Trail Run/Walk

Flanders is excited for its 11th Anniversary Field & Forest 5K Trail Run/Walk on its property in Woodbury, CT. The 5K run/walk is a fun event, which exposes community members to the Flanders Van Vleck Farm & Nature Sanctuary. It promotes health and fitness, capitalizes on the growing interest in trail running/walking, and raises funds to support Flanders' mission to provide opportunities to appreciate nature’s wonders and preserve land, inspiring lifelong learning about our natural world.

Walk/run through the woods and fields of Flanders, officially timed by Fast Track Timing. Celebration after the run includes live music, food trucks, and more!
