The Northern part of Queen's park is an excellent place to jog, walk, or run. I've tried to research the distance of this loop, and I've uncovered conflicting information. Some people think that the running loop is 1 full mile, or 3/4 of a mile, or approximately 1 kilometer. Lately I've been running the loop and I would say its just shy of a 1 Km. (probably closer to 900m).
Nonetheless, its a great little loop for shorter runs, or for those who need to measure the distance of their workouts.
I did 15 laps of Queens park today...but I won't be able to walk tomorrow. I hope it works out better for you.
Go Run.
