The Sun Marathon 10K is an out and back on the marathon route that starts and finishes at Gubler Park in Santa Clara, Utah. Runners head out against the marathon direction and return the way the marathon runs, with red rock mountains in view throughout. It is the second-shortest distance on race weekend and runs after the marathon and half marathon fields have started.
