Tough Turtle is Ithaca’s original adventure obstacle course race with 5k and 10k courses. The event is presented by CFCU Community Credit Union. Tough Turtle serves as a celebratory community event and opportunity to support a critical local cause: inspiring the next generation of environmental stewards. The 5th annual Tough Turtle celebrates the milestone anniversary with a new 10K option and new and challenging obstacles. Also new this year is a post-race celebration sponsored by CTB/Ithaca Bakery and Ithaca Beer! Climb, sprint, crawl and slide through the course along the Cayuga Waterfront and Black Diamond Trails. All this takes place on the south shore of Cayuga Lake.
