About this race

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.  

Please Note: There will be a bike cut-off time limit for athletes on course.  You must be OFF the bike course within 2 hrs and 45 minutes of the start of the second wave.  If you have not completed the course in the allotted time, you will still be allowed to run 1 loop of the run course, but you will not be eligible for any awards.
