I only have one route i follow regularly. Usually start around bullock + 48 and go down to the airport and back. I ride through the subdivisions, along raymerville, down manhattan, carlton... and then i stop paying attention to street names. About 27 km.

I find this route the best route inside the "city." The roads are in good shape, the houses help block the wind, and the traffic is relatively low and is slow moving.

When i go mountain biking, and don't feel like going anywhere, i ride on a trail i built up with my friends around 48 and 407. loops around milne, to mccowan, then back under the bridge @ 48, down to 9th + 14th, and back to 48. About 9 km.

when i have more time (summer) i plan on going places... like newmarket, or the zoo, or wherever. depends on the day.

And thanks for the responses so far!
