OKLAHOMA CITY - It's been voted one of the 12 'must run' marathons in the world - the Oklahoma City Memorial Marathon which kicked off Sunday morning.
It was 26.2 miles to remember the 168 people who were killed in the Murrah Federal Building bombing on April 19th, 1995.
Mother nature didn't want to cooperate early on, but the weather could not dampen everyone's spirit.
Strong thunderstorms, including hail, may have delayed the start, but perseverance conquers all.
Nearly 26,000 runners eventually participated.
The marathon was set to begin at 6:30 a.m., but was postponed until 8:20 a.m.
Some had the eye of the tiger, with a little help from supporters offering water along the way.
Some were cheering on their courageous moms - and there was encouragement of all kinds.
The feeling of crossing the finish line is unforgettable.
"It's absolutely amazing," one runner said. "Just coming down the hill and seeing everybody cheering. They don't even know you. It's awesome."
The winners - Jason Cook, 32, won with a time of 2:42:29.
Cook placed third in last year's race.
The women's winner was Camille Herron, 32, who placed fourth overall with a time of 2:51:20.
Herron set the women's course record in 2012.
Both runners are from Norman.
