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.

The majority of this route is the same as Georgetown 76 km. It starts and finishes at the Gellert Community Centre. It still goes along one of my favourite roads, Sideroad 15 and you still climb Watson Rd. The first place it deviates from the other route is right after the Watson Rd. hill. Rather than go straight on Watson Rd. towards Arknell, you turn onto Maltby Rd. then turn up Victoria and then turn onto Arknell where it joins up with the other route at Arknell and Watson Rd. That will add an additional 4 km to the route. It will also allow you to get refreshments at the variety store at the corner of Victoria and Arknell. The bigger addition is still to come. Also, if you don't feel up to the task of climbing Watson Rd., you can keep going straight on County Rd. 34, turn right onto Victoria and meet up with the route at Victoria and Maltby.

The big addition of this route comes at the junction of Regional Rd. 43/Sideroad 22 and 4th Line. Once you turn at the bottom of the hill, and be careful coming down that hill, there's not much room for run out, you keep going straight on 4th Line rather than turning back onto Regional Rd. 43/Sideroad 22. This will take you further to the north where you will turn right at Erin Halton Hills Townline. In fact, you can't go much further north if you're on a road bike because the road turns to dirt. Within 1.5 km you'll be turning back down south again on 5th Line heading towards Limehouse.

If you're going to get lost anywhere on this route it's going to be in Limehouse. I speak from experience. If your goal is stay on route as planned please be mindful of where you turn. You will go down a good sized hill into the little hamlet of Limehouse, and then go over a small bridge. Do not go straight once you are over the bridge, turn left at the little church to get back onto 5th Line. After you turn left onto 5th Line you will come to a hill, which, for many of you, will probably be an out of the saddle climb. If you don't come to it soon backtrack to get yourself back on route.

It's in Limehouse where you'll meet up with the shorter Georgetown 76 km route. Overall, you will add another 17 km over the original route. This is a great route. It's not that hard to follow, it has some good climbs, the terrain is rolling and you really feel like you are in the country for most of the route.
