LAKE TERRAMUGGUS OLYMPIC DISTANCE TRIATHLON
August 15, 2026
8:00am
Join us for the Lake Terramuggus Olympic Distance Triathlon! This is the perfect way to celebrate a summer of training and racing at the Lake Terramuggus Sprint Series - with limited adaptation to our sprint course this Olympic race will be familiar to those participating in the sprint series throughout the summer. Even if it is your first time to Lake T this race is fun and fast, moderate hills on the bike and run. A great race for your first Olympic Distance Tri!
This race will be a 1600 yard swim, 25 mile bike and a 10K run. This event is designed with the same mission as the Lake T Sprint Series - to encourage participation from all levels of triathletes, provide a great training opportunity and foster a community of athletes.
