Story

The 2 Mile Story

3 High School guys toe the line for the start of the guy’s 3200 at the State Meet; each with their own unique goals. Rafferty: a freshman who came into the season with the goal of breaking the school record. My words to him were it won’t happen during your first attempt but we can get there this season. Sam: a Senior who played baseball for 2 years and then COVID kept him from having a junior track season. He is looking to set a PR to finish his one and only Track season. Will: also a Senior who has done well with shorter distances but has at times struggled to complete the longer distance races. His goal, introduced by me but agreed upon by both of us, is that he will complete the race!

What I love about this story is that all 3 guys met their goals!  A new school record by over 10 seconds for Rafferty, a triumphant PR for Sam, and the one that makes my heart sing just a little sweeter…In spite of wanting to quit, Will took a walk break instead and was able to cross the finish line and completed his final HS race! 

For me as a coach, setting and accomplishing goals is a piece of a larger puzzle. Sharing the ups and downs of the journey and learning life lessons are where the magic happens!
