Chuck Coffey rejoined the Union College mountain biking program as he was named the team's head coach in January of 2002.

When the program first formed in the 1998, Coffey served as the Bulldogs' first head coach. After a four-year hiatus, he returned to assume the position once again.

In addition to being familiar to the Bulldog program, Coffey has been involved with cycling and mountain biking for over a decade, having owned a store that specialized in mountain biking for 12 years.

Under Coffey, Union enjoyed its most successful year in 2002. The Bulldogs won the NCCA Division II National Championship - the first team national championship in school history, and Amanda McKay won the NCCA Division II Women's Individual Omnium National Championship. In 2003, the Bulldogs placed third overall at nationals, while McKay won the women's cross country national championship.

Union placed sixth at nationals in 2004. In 2005, Coffey had two riders place in the Top 5 in the Omniums with Chrissy Buerkel placing fourth in the Women's Omnium and Travis Mullen finishing second in the Men's Omnium. Buerkel also won a national championship by winning the women's cross country race. In 2006, McKay captured the short-track national championship as she placed third in the Women's Omnium.

Union recorded a fourth-place finish for the second year in a row in 2007 as Greg Gibson came in fourth in the Men's Omnium.

Coffey has had a total of eight riders to be named an NCCA All-American.

Since its existence, the Union cycling team has just focused on the mountain biking aspects of the sport: cross country, dual slalom, and downhill.
