Holiday 5K & 10K at Knoxville, TN

Holiday 5K & 10K at Knoxville, TN takes place in Knoxville, Tennessee, on December 26, 2026. Two formats share a single 8:30 a.m. start: a 5K (3.1 miles) and a 10K (6.2 miles). The day after Christmas is an easy one to build a run around, and the simultaneous start keeps the logistics simple.

Choosing between the two comes down to how your December has gone. If your weekly mileage has held up, the 10K gives you a better read on your fitness heading into the new year; if the last few weeks have been patchy, the 5K is the honest choice and far less punishing. Runners doing the 10K should settle into a rhythm they could hold for an hour and only think about pushing after the four-mile mark. Either way, this is a good reset run before January training starts in earnest.
