From the Organizer
How many people can say they’ve jumped off the Star of Knoxville Riverboat INTO the Tennessee River? Who can say they’ve gotten to swim under five historic bridges, past Neyland Stadium, and the Knoxville skyline, finishing through beautiful river bluffs lined with historic homes, in gorgeous Sequoyah Hills?
Now’s your chance!
Bridges to Bluffs is a premier 10K downstream open water swim and a proud leg of the Tennessee Triple Crown Open Water Series (alongside Chattanooga’s Swim the Suck and Huntsville’s Swim Hobbs Island).
