About the Event

Are you ready to TRI KNOX again?

Sprint: 1000M Swim - 14 Mi Bike - 5k Run
Olympic: 1900M Swim - 25 Mi Bike - 10k Run
Half: 2200M Swim - 56 Mi Bike - 13.1 Mi Run

The sprint will be a DOWNSTREAM 300 meter swim ending at Suttrees Landing dock. The bike ride will head up Island Home for a 14-mile tour of some of S Knoxville's finest scenery. the run will take off along the riverside through the historic Island Home neighborhood onto the Will Skelton Greenway. Expect a little elevation, or as we say "Gently Rolling Hills" on this run, but in the shade and along the breezy river. Cruise back to the finish line in Suttree's boardwalk and celebrate with Knoxville's finest!

The olympic distance will also include a nice DOWNSTREAM swim from Island Home to Suttree's and head out on the same bike path for a 25-mile tour of scenic roads. The run will follow the same path extending just past Meads Quarry parking and follow its way back to Suttree's Landing as well.

The half-iron distance will also start from Island Home with a brief 100-meter upstream swim before heading downstream to Suttree's. The bike route showcases the beauty of the South Knoxville countryside. Once back the run will follow the same path as you make your way past Meads Quarry to the Forks of the River and follow its way back to Suttree's Landing as well. The half-iron distance will have a cut-off of 8.5 hours with a bike cut-off of 12pm
