Erin O'Reilly is in the midst of her ninth season as the assistant coach for the Boston College women's cross country and track and field programs. In her time at the Heights, O'Reilly has coached a slew of Eagles to three Atlantic Coast Conference individual championships, a pair of Eastern College Athletic Conference (ECAC) titles and numerous NCAA appearances.
Under O'Reilly's tutelage, Boston College phenomenon Caitlin Bailey competed in NCAA finals of the 800-meter. The back-to-back outdoor 800m ACC champion qualified for the national meet eight times throughout her career as an Eagle; doing so as an NCAA Regional runner-up in 2010. At the regional meet, Bailey established the BC record at said distance with a time of 2:03.45. O'Reilly also guided Bailey to the indoor 800m record (2:04.66) in 2009, the third fastest 1500-meter time in school history (4:21.53) in 2010 and a 2011 Outdoor ECAC Championship. Additionally, O'Reilly was instrumental in helping the 2010 distance medley relay team to an 11th place finish in the country.
The 2009 season saw another of O'Reilly's protégés, Anna Cioffredi, become the first freshman from Boston College to place the finals of the 400-meter at the ACC Championship. In the final, Cioffredi clocked a 54.82 - the fastest time of any Eagle in 15 years and fourth best in school history.
During O'Reilly's tenure, other standouts have included Melissa Sherman - who became the first Eagle to win the BIG EAST championship in and qualify for nationals in the outdoor 800-meter event in 2005 - and Kathleen Smyth - who captured the 1,000-meter crown at the 2005 ECAC meet.
In 1994, O'Reilly began her collegiate coaching career as the graduate assistant for her alma mater, West Virginia University, before being promoted to assistant coach. From then until the time she left in 2002, the Mountaineers earned 22 All-American accolades, won 19 ECAC individual and relay championships and 13 All-Mid Atlantic Region honors on the track and on the course.
In 1996, O'Reilly became the long sprints and middle distance head coach for the AAU Youth Track Program's West Virginia Flyers. There she trained two All-Americans for the 2000 USATF National Championships. A year later, O'Reilly was named the co-director of West Virginia University's Cross Country Camp of Champions.
From 1993 to 1998, O'Reilly also held the position of post-collegiate Olympic Trials Coach. As such, she was responsible for the training regimen and evaluation of Trials athletes. In addition to daily coaching, she was charged with the tasks of finance management for the program and recruiting. Throughout that time period, O'Reilly was also a member of the NCAA Mid-Atlantic Rankings Committee.
O'Reilly earned a Bachelor of Science in Physical Education from West Virginia in 1993 and returned to complete a Master of Science in Athletic Coaching in 2001.
A former student-athlete, O'Reilly built an impressive resume in her time as a Mountaineer. After working her way to be named captain of the cross country and track and field programs in her final season, she went on to become the Atlantic 10 champion in the mile and 3,000-meter competitions - simultaneously establishing conference records in each event. As early as her sophomore year, O'Reilly was an NCAA Provisional Qualifier in the 3,000-meter and had won the 1,000-meter title at the ECAC meet. By the end of her collegiate career, she held seven school records in cross country and track.
