Muskoka 1/2 Iron Man Swim 70.3
This is footage of the start of the 2009 Muskoka 1/2 Iron Man in Huntsville, Ontario, Canada. It features a couple angles of the swim segment.
You can see the heats of swimmers lining up for their start while others are either waiting for their staggered start or are already in the water. Keep an eye for swimmers when they exit, are assisted out of the water and run uphill to the transition area in the parking lot of Deerhurst Resort.
