Course Map

The 5K starts at Avenue B and 3rd St West. Head north, going up the hill to Parkhill and then run west. Just before 13th St West, turn around and head back to Pioneer Park. Turn right on to 3rd St West and head back down the hill. Enter the park on the paved path just north of Daylis Stadium, follow the path around to the finish line. You'll see the Competitive Timing arch.

The Kid's one mile fun run will use the sidewalks and go the perimeter of Pioneer Park. While not wearing bibs, the kids will cross the same finish line as the 5K event.
