The Oklahoma City Memorial Marathon combines the personal challenges of running a marathon with the emotion of a shared national tragedy. Runners and walkers of all levels can participate in a relay option as well as a kids marathon, half marathon, senior marathon and Memorial 5K.

The Health & Fitness Expo kicks off race weekend festivities. It opens on Friday for packet pick-up and runs through Saturday. The Expo is open to all and features dozens of vendors with the latest in running gear and apparel.

All event proceeds benefit the Oklahoma City National Memorial & Museum.
