Colin Harrison is a Silver-graded sportscar driver in his third season of racing, active across three series since 2024 with 35 starts to his credit. His Racer Rating of 2,271 places him in the amateur-to-early-professional range within endurance and GT racing. Harrison competes primarily for TechSport Racing, which has fielded him in 20 of his starts across two series; the team's roster includes drivers of mixed ability, with its strongest competitor rated considerably higher. Harrison's average finish of P5.3 reflects consistent mid-field performance, and his record shows he is a competitive regular in his field rather than a frontrunner.[1]
The bulk of his success has come in McLaren Trophy America, where across two seasons he has recorded three wins and nine podiums from 14 starts. In the more competitive Mustang Challenge, he has managed one podium from 16 attempts. His head-to-head record against his most frequent rivals tells a clear story: against drivers of similar or slightly lower rating, Jeff Cook, Deniz Teoman, and Tate Pritt, he holds winning records, finishing ahead of them consistently. Against stronger competitors, he is outpaced; he has finished behind Devin Anderson and Sandy Satullo in the majority of their shared races, both of whom rate substantially higher. Notably, Harrison has occasionally crossed above his weight class, with podium-level results against several Silver- and Bronze-graded professionals including Michael Cooper and Austin Krainz, though these remain isolated occurrences rather than patterns. His 2026 Mustang Challenge season has been less successful, yielding no podiums in six rounds as he settles toward the back of a competitive field.
