June 20th is the longest day of 2016, June 18th is the longest Saturday of the year so it makes sense to do the Longest Ride that day. 400 mile relay ride with 3 IMRG Chapters. Knoxville to Murfreesboro to Chattanooga. Knoxville will leave out to.join up with Murfreesboeo then our two groups will join up with Chattanooga and back to Knoxville. Murfreesboro and Chattanooga will continue the relay until they complete the loop. C'mon out. You can stay tuned at Indian Motorcycle Riders Group of Knoxville's Facebook page or email us at [email protected].
