Coach Karen Bryant has been coaching girls cross country since the fall of 1996 and has been the head coach since 2002. Her goals for each year are to have each girl improve individually and as a member of the team, and for each girl to recognize that running is a lifelong sport. The workouts are tailored to where each runner is within her training and experience. Cross country is a sport that allows each runner to see how the effort they put in pays off in results in races. A runner has the chance to watch her own skills develop while always playing a role in the team's success. Several students have on to run in college and truly embraced running as a lifelong sport by competing in races and marathons after leaving St. Mark's.
