What is the age limit for the races?

Participants in the marathon must be 16 years of age or older on race day.

What is the course time limit?

All participants finishing the marathon and half marathon within 7.5 hours will receive an official finish time. However, please be advised that the marathon and half marathon course will reopen on a rolling schedule based on a 16:30-minutes-per-mile pace for the last runner to cross the start line. For example, participants should have passed the 2-mile mark 33 minutes after the last runner has crossed the start line, should have passed the 6-mile mark 99 minutes after the final corral has crossed the start line, etc.

The course must reopen to traffic on this schedule in order to be courteous to our community. Participants who are unable to maintain a 16:30-minutes-per-mile pace will be asked to move to the sidewalk at the discretion of our police officers and may not have access to aid stations.

Marathon Relay

For those participants who want to experience all of the marathon course but aren’t quite ready to complete the entire event, we offer the marathon relay! Teams of five runners complete relay legs of 5-6 miles each and finish the marathon together! Click here to visit the Marathon Relay page for more information. Learn more about the Marathon Relay here.

Boston Qualifier

The Williams Route 66 Marathon is a Boston-qualifying race that is run on a USATF Certified Course.

Start Corrals

In order to provide the best possible race day experience for all participants, the Williams Route 66 Marathon utilizes a corral system at the start line of the marathon, half marathon, and marathon relay. Participants will be assigned to one of four start corrals based on their projected pace, which helps keep the course flowing smoothly on race day. All race registrants are required to submit past and projected pace information at the time of registration to allow the race committee to properly assign corrals.

The four corrals are designated by the letters A, B, C, and D, which are marked at the start area and on each athlete’s bib. ALL PARTICIPANTS MUST ENTER THEIR CORRALS AT THE BACK OF THE CORRAL. The corral area can be a little confusing if you aren’t familiar with it, so we recommend that all participants review the Start Line Map on page X and arrive early to make sure they have time to find their corral. CORRALS WILL CLOSE 5 MINUTES PRIOR TO THE START OF THE RACE. NO EXCEPTIONS.

NOTE: ALL PARTICIPANTS WHO REGISTERED AFTER OCTOBER 1, 2020 WILL BE ASSIGNED TO CORRAL D. If you wish to change your corral, simply stop by the Solutions Desk at packet pickup and request a corral change. If remaining space is available in your preferred corral, you will be authorized to change.

Athletes will only be admitted into the corral that corresponds to the letter on their bib. Once in their assigned corral, athletes should line up by pace according to the signs posted in the corral. This helps keep traffic moving forward on race day!

We love when our participants want to race alongside their friends and/or training partners on race day! However, if participants desiring to race together are assigned to different corrals, they must all start in Corral D. There will be no exceptions.

Hand cycle and wheelchair athletes will have their own separate corral at the start line that will be placed in front of the elite athletes. Hand cycle and wheelchair participants will start at 8 am. Participants in Corral A will start at 8:02 am. Participants in the following corrals will start at 5 minute intervals thereafter. Don’t worry, there will be confetti blasts for every corral!

Family Reunion Area

We know walking after you cross the finish line can be a struggle, so we try to make reuniting with your loved ones as easy as possible. We recommend meeting at the Family Reunite Area located on the south side of Guthrie Green, along M.B. Brady Street. We know your family and friends will be ecstatic to see you when you cross the finish line, but unfortunately, we cannot use the public address system to reunite participants with their families. Therefore, please make sure to arrange a convenient meeting spot with your loved ones prior to the start of the race.
