Park & Start at Panera Bread, 4403 Roosevelt Blvd, Jax. The run starts at the south end of the shopping center, up and over the Roosevelt Bridge. It follows most of the original Ortega River 5K course but with a different start/ending. The run includes two bridges on a relatively flat (a few gentle ups&downs) shady circular course. There are two city parks with water stations on the course.
Meet & Start at 9840 San Jose Blvd, Jax. This is the annual Thanksgiving Day 5K course, also used as a very safe 5K training course on the neighborhood streets of Mandarin. Park in the lot behind the Krystal restaurant.
