Riding from Ajax, I was trying to find a route that took me through the most parks as possible, even if it added extra distance. Also I was looking for the best way to get through the don valley area without resorting to the major roads with their busy bridges. It's easy to lose one's way in many of the windy parks, with many trails. Trip took me about 4.5 hours, riding not very strenuously, and getting lost and doubling back several times.by xxvii
