Jogging trails in Toronto

As part of my exercise routine I jog twice a week on the small residential streets around my house or on a treadmill when the weather is not being kind. This is enough to keep my heart exercised, however, lately I have been entertaining the idea of completing a half marathon, and the training requires jogging for one hour at least once a week. Spending an hour on a treadmill or making circles around  the block is quite boring, so I turned for help to my good friend, the internet, in search for nice jogging trails in Toronto. Fortunately, Toronto is a pretty green city with many parks and recreational areas. Two of the longer routes I found are described below. The descriptions of these and other trails can be found here. Great PDF maps of the recreational trails are provided here.
