Records & Results

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.

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.

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.
