Once David Cooper won his first individual NCAA Division III national title in 1997, an indoor 5000 meters title, there was no looking back for the final two years of his career at Mount Union. Between the 1997 and 1998 indoor and outdoor campaigns, the Parma, Ohio, native amassed seven national titles ranging from the indoor 1500m to the outdoor 10,000m twice, and 13 total All-America honors (including two from cross country). He claimed both the outdoor 5000m and 10,000m national titles in back-to-back seasons in 1997 and 1998, earning him the distinction of being the most recent of only three Division III men to have accomplished that feat. Sandwiched in between those outdoor sweeps came a 1500m/5000m sweep at the 1998 indoor championships – the first and only time that feat has been accomplished, even when considering the current mile event rather than the discontinued 1500. An OAC cross country champion four times over, Cooper still holds indoor school records in the mile and two mile and at 3000m and 5000m, as well as an outdoor record as a member of the 4×800m relay. Cooper ran professionally for Puma and Brooks as a post-collegian.
