First of all I love the word "wog" and plan to steal it LOL! And the embarrassment that you felt is understandable... we psych ourselves up, pep talk, all that good stuff to be "ready" for anything that we decide to throw at ourselves and anything less than what we expected can feel like a failure. Just remember, you finished a 5K! OMG do you realize how awesome it is just to have finished it?! No matter how long it took you, be proud that you did it and you can only improve from here
