Zone 5 Map Some consider this zone to be the heart of cycling in Southern Ontario. The north is bordered by Hwy. 7, the south hugs the shores of Lake Ontario, the east follows Hwy. 6 and the west follows Hwy 10. I have chosen four locations as starting points. Hornby Park is the kick off area for the Halton Hills, Gellert Community Center is the start for routes out of Georgetown, Campbellville is the start for routes in that area and the Carlisle Community Center is the starting location for routes out of Carlisle. The routes in all four of these areas often criss cross each other and will sometimes use the same roads.

Some of the steepest climbs in Southern Ontario are found in the Halton Hills. The road up to Rattlesnake point reaches gradients of up to 25%. You won't find this hill on any of the routes....yet. The escarpment in this area is steep enough for rock climbing so it is reasonable to expect climbing on steep gradients. The roads here tend towards the "tar and chip" variety which is fine after a season of settling. Be cautious of cornering during the first season of resurfacing as there will be lots of loose gravel at the side of the road and on the corners.

One of my favourites rides is along 15th Sideroad out of Georgetown. Here you will find steep, out of the saddle climbs, but fairly short. This road is very rural and has enough twist and turns to add some extra excitement.

This is probably one of the better starting locations due to the proximity of the Gellert Community Centre and how close it is to top notch, country cycling. The washroom facilities are extremely clean and they offer reasonable hours of access. I've provided a link for the swimming schedule at the Centre (look in the "Quick Links" section below) as this pretty much determines when the facility opens and closes. You'll soon find that after leaving the community centre the country is close at hand. Within 12 km you will turn onto Sideroad 15, which happens to be one of my favourite roads to cycle. It has descent size hills, some good, fast corners, is relatively quiet and has a fairly good road surface.

Another good section of the route is Nassagaweya Townline and 25 Sideroad. The rolling hills offer plenty of opportunity to test you climbing legs, although none of them are too large to warrant a categorised rating. The area feels slightly off the map as it is quiet and sees very little traffic. There are a few bumps and potholes along the way so be vigilant and keep your eyes on the road.

One of the bigger climbs of the day can be found near the end of Sideroad 20, just before you turn right onto Nassagaweya-Esquesing Townline. It is definitely a good punch and will have you out of the saddle. Gradients will hit the double digits at the steepest part of the climb. There is a small bench half way up that will offer a small respite as the gradients ease up, but they quickly ramp up again and will be sustained all the way to the top.

At the 54 km mark you will come to a steep downhill section. There is a sharp corner mid way down that will force you to hit the breaks. Also, there is no run-out at the bottom, in fact, the hill pretty much stops at 4th Line, where you'll be turning left. Take it easy on this one. It's easy to gather enough speed where stopping might become problematic, especially in wet conditions. At the 56.1 km mark you'll enter Limehouse where the steepest climb of the day awaits your arrival. You'll cycle through a very small Hamlet toward a very narrow road that doglegs to the left. The climb is short and steep.

The only drawback to this route is the availability of water. When cycling in Southern Ontario in the summer months, temperatures can average somewhere near the 30 degree Celsius mark. Getting water is paramount. There are two places to stock up. The first is at the 21.4 km mark at the corner of 15 Sideroad and Guelph Line at the gas station. The second place is at the 24.1 km mark at the corner of 15 Sideroad and 1st Line (Nassagaweya) in Moffat.
