I'll be in Markham, north of Toronto, from May 16 to May 21. I'll be bringing my bike, and I'm interested finding some good road riding. Preferably routes of 20 to 30 miles. Could anyone recommend anything within a 30 minute drive of Markham? I'm interested in rural roads, if possible. I'll be heading out at 5:30 AM each morning, so traffic shouldn't be a problem.
