Runners follow a point-to-point course at the Williams Route 66 Half Marathon, which starts with the full marathon at the corner of 7th and Main Street downtown, and shares the same route for most of the course — just before the finish, runners in the half marathon turn off to Cameron Street to complete the race, while those running the full marathon continue on for another 13.1 miles. In between, the race unfolds through city parks and downtown neighborhoods, including a long, flat stretch along the Arkansas River and a bridge crossing along Route 66 proper in the last few miles.
