That is awsome! i know what its like to push yourself to a physical level and the personal satifaction you get from it..im not a runner type,more on the anarobic side..national bodybuilding/weightlifting...won some.. lost a lot! but i do know when i included cardio in my training to loss bodyfat, i suffered more on the road runs and mt bike rides than i ever did under a loaded squat rack or bench press!... congrats on your event and hope you keep beating yourself in future meets!!
