A $6-million renovation to the Harold Alfond Athletic Center gave Colby one of the finest facilities in the Northeast, and recent reconstruction projects have upgraded playing fields and tennis courts.

The athletic center includes the 3,000-seat Wadsworth Gymnasium; the Alfond Ice Arena; a field house with four indoor tennis courts, a 220-yard track, room for indoor practices, and a climbing wall; five international glass-backed Dunaway Squash Courts; the Carl Nelson Physical Therapy Center; a 25-yard by 25-meter pool; a 5,300-square foot fitness center brimming with state-of-the-art exercise machines and weights; and a spacious aerobics and dance studio. A conference room provides space for gatherings and a home for Colby's trophies and awards. Outdoors there are 50 acres of playing fields, including the lighted Bill Alfond Field (synthetic field), a lighted practice field, an all-weather 400-meter track, 10 outdoor tennis courts, and the 8.5-mile Campbell Cross Country Trails.
