MEC Toronto Race Four
MEC's Toronto Race Four has something for everyone: a 5k, 10k and half marathon, all taking place in the beautiful Tommy Thompson Park on the Leslie Spit in the east end of Toronto. The 5k and 10k just cost $15, MEC's standard registration rate, and the half marathon will only set you back an additional $5. You really can't beat a $20 half marathon on a scenic, flat and fast course.
All three races start at the entrance to Tommy Thompson Park and head out along the spit with varying turnaround points.
