How to run
While online registration for the race is closed, runners may register at the Health and Fitness Expo at the Cox Convention Center downtown Friday and Saturday while spots remain open.
As of the weekend, spots remained open in the marathon, half marathon and marathon relay.
Marathon registration at the expo is $130 per runner, while the half marathon is $100 per runner and the marathon relay is $325 per five-person relay team.
How to volunteer
After Monday's event in Boston, marathon organizers had a rush of inquiries from people who wished to volunteer.
Because of that push, the event has fulfilled its needs of approximately 3,000 volunteers for the event. The volunteers work at packet pick-up before the race and at water stops and the start/finish line during the race among other responsibilities.
Marathon organizers are asking anyone who wants to volunteer and be a part of the race to support the runners on the course.
How much money does it make, and where does the money go?
The Oklahoma City National Memorial and Museum is the sole beneficiary of Oklahoma City Memorial Marathon proceeds. The Oklahoma City Memorial Marathon has contributed more than $4 million to the Memorial since it began in 2001. The breakdown of the contribution by years:
What else is new this year?
In addition to redesigned medals and shirts, there are several other changes in the Marathon for this year's race:
*The full marathon and half marathon groups will be split on Classen from 50th Street to the finish. In previous years, there was no separation between the groups.
*While the course has remained relatively unchanged since the event began in 2001, construction on Waverly Avenue between Wilshire and Britton necessitated a change this year. Instead, the course will use Glenwood Avenue before merging back onto Waverly.
*Embrace the Race. The program for businesses along the marathon route was in place last year, but organizers have made it an emphasis this year, providing businesses along Automobile Alley on Broadway and others along the route packets with cowbells, window clings, flags and Koozies to show their support for runners as they pass.
