TULSA, Oklahoma - The gun sounded at midnight as 174 runners pounded the pavement all with the same cause of finishing a 50 mile race.  The five loop course started at 41st and Riverside and went north to the 31st bridge then south up Turkey Mtn, and back across 71st to the river trail.  Many of these runners had never run a full 26.2 mile marathon.  In some cases ignorance is bliss, happy faces gave way to tired blistered feet.  The winning runner was Steven Richard who clocked a time of 7 hours 20 minutes.
