Adam Mancini

Adam started running about 20 years ago and fell in love with it almost immediately. He competed in cross country and track in high school and at the Division 1 level in college.  He attended the University of Detroit Mercy and walked on to the cross country team. Over 5 years at the school and hard work, he earned a full athletic scholarship for his last two years of eligibility.  He continued running after college and has completed numerous road, track and trail races. Adams PR’s are 1:54 for 800 meters, 4:06 for 1500 meters, 4:28 for the mile, 15:56 for the 5k, 27:15 for the 8k, 35:23 for the 10k, 1:18 for the half marathon and 3:09 for the full marathon. Over the past few years, he has been focusing on triathlon, although running remains his true passion.

While competing for himself, Adam realized he had a lot of knowledge and experience to pass on.  With this in mind, he returned to his high school alma mater and took over a failing boys track and cross country team. In 2 short years, he brought the boys team past their struggles and recorded league championships and state qualifying teams in both cross country and track.  Since moving to Virginia in 2005, he has coached at the high school, middle school and community college level.

In addition to running, he participates in coed softball, soccer, and flag football.
