Sean O’Leary

Sean’s racing career initially experienced a failure-to-launch following a request to quit soccer in the 2nd grade. According to legend, the sole reason given was that soccer entails “too much running.” Sean eventually saw the error of his ways under the tutelage of Coach Tom Martin at Walter Johnson High School, and later as a member of the University of Maryland cross country & track teams (yes, UMD used to have a cross country team). 

Sean has been a member of GRC since 2014, and has a particularly soft spot for the half and full marathon distances. Outside of running, Sean works in business development for a sustainability startup and plays a mean bass guitar. Coach Jerry has erroneously dubbed Sean as the “most famous runner in Montgomery County history”. For the record, he is NOT the most famous runner in Montgomery County history, not by a longshot.
