MEN’S EVENT RECORD HOLDER
Jon Sinclair won the inaugural William A. Irvin 5K in 1994, and his time is still yet to be beaten.
Sinclair crossed the line in a time of 14:43, just three seconds ahead of runner-up Jorczak. As it turns out, that’d be as close as anyone’s ever come to breaking the mark set by Sinclair.
The 15:00 mark has been broken four more times, once by Jorczak in 1995, but Sinclair’s mark has withstood the test of time in what’s now become the kickoff race to Grandma’s Marathon weekend.
NOTE: Jesse Chettle again broke the 15:00 mark in 2022 with a winning time of 14;52, but a course management error resulted in that year’s racecourse being short and thus invalidated the results in terms of official records.
Before running in Duluth, Sinclair was a two-time All-American runner at Colorado State University and in 1989 was inducted into the school’s Athletic Hall of Fame.

WOMEN’S EVENT RECORD HOLDER
Duluth native Katie McGee won the first three titles at the William A. Irvin 5K from 1994-96, and she set a still-standing event record in the process.
McGee’s time of 17:11 in 1996 was challenged by the following year’s champion Sara Rhode, who also finished in 17:11 but just hundreths of a second slower than McGee. Since then, the closest anyone’s come to challenging McGee’s mark was in 2016 when Sarah Crouch ran 17:21.
NOTE: Nikki Long’s time of 16:15 in 2022 would have broken McGee’s event record, but a course management error resulted in that year’s racecourse being short and thus invalidated the results in terms of official records.
In 2022, McGee was presented with the Ron Daws Ambassador Award in recognition of her connection to Grandma’s Marathon weekend and her lifetime of work to help the event be successful. After using the racecourse as a training ground while growing up, McGee now has finished 13 Grandma’s Marathons and also, for a short time, taught an online marathon training class at Lake Superior College to help more beginning runners prepare for the big race.
