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.

Your ride out of Campbellville will be mostly flat for the first 2 km. After you turn left onto Twiss Rd. you will have a noticeable climb for about 1.2 km until you turn right onto Side Rd. 3. This small section of road, just shy of 2 km, is probably one of my favourites roads in Southern Ontario. It's small, quiet, the trees overhang the road, it twists and curves and goes up and down; it has everything. There is one thing to watch out for in the spring and that's a coating of sand that may still be covering the road left over from the winter sanding operations. So be careful, going down and around the corners.

A series of back-roads will bring you onto a slightly busy Centre Rd. I say busy because the roads up until now have been really slow and mostly traffic free. As you turn right from Concession Rd. 11 onto Centre Rd. it becomes clear the road goes up. The rollers, which are not that steep, will last for about 6.5 km until you turn onto Concession Rd. 9 (aka. Victoria Rd. S.). After this point things will level out and you can regain your breath.

The northward journey up to Regional Rd.34 on Victoria Rd. also has rollers, but they are small and easy to negotiate. As you turn right onto Regional Rd. 34 you'll notice this road is certainly busier than what you have experienced so far. It's one of those necessary "link up" roads that are hard avoid in certain situations. Put your time trial helmet on and sprint the 2 km to Watson Rd. where you will turn right. Watson Rd. is much the same as Victoria, except you are now heading south. The break in the route comes at around the 34 km mark at the intersection of Watson Rd. and Leslie Rd. You can either keep going south and suffer the hills ahead or turn left and refer to directions on the alternate route Campbellville 44 km.

If you decide to head south a good size climb is staring you right in the face. Once on top you'll have a fantastic view of the rolling terrain and the farms that dot the landscape. The descent has a few quick bends, but be careful of the sand that may be present on the road. After you turn left onto Centre Rd. (which isn't marked) you head south toward your final challenge of the day; Mountsberg Rd. What you are about to climb is immediately obvious as the hill is hard to miss. As you climb the hill in front of you, you can think about the next one, which is just up the road that is equal in both size and gradient. Both climbs are unrated, but I think they should at least warrant a Cat 5.

Once you have regretted taking the hard way a few quick turns will bring you back to Campbellville Rd. and 1st Line where you will meet up with easier alternative route. Back together again, a short, flat ride will bring you back to the cars.
