Varsity Ultimate Frisbee

Program Overview

Ultimate Frisbee Program

Ultimate Frisbee is the quintessential team sport — student-run, coed, and built around a "Spirit of the Game" that prizes belonging, kindness, and collective growth. Every layout grab and flick pass depends on a shared commitment to mutual respect: instead of referees, players officiate their own games, a tradition Ultimate players have carried worldwide for decades. Coaches collaborate closely with team captains on practice plans, but the culture, energy, and self-governance on the field belong to the players. On the turf, Highlanders don't just compete — they practice character and sportsmanship as much as athleticism.

The program welcomes newcomers and experienced players alike: no prior experience is required, and compared to other varsity sports, daily practices and a lighter travel schedule make it one of the more manageable time commitments on campus. For students looking to try something new in a supportive, encouraging environment, Gunn's Ultimate Frisbee team is an easy way in — and a distinctive one.
