I don't know if anyone is interested or not, but I'm thinking of organizing a Practice Crit at CB South High School (Warrington, PA) on select weekend days. I've included a map of the course. Check it out. It's relatively flat (only 50 ft. elevation change per lap), and just shy of 2 miles per lap. I figure a 10-lap race would be a good workout and good experience. If you're interested, email me: firstname.lastname@example.org I can tell you for a fact, that we'd either have this training race on either a Saturday or Sunday morning...EARLY. Like 7 a.m. early to avoid any kind of traffic. It is NOT a closed course, and there is traffic on 3/4 of it. In fact, there is one section that is approximately 200-300 yds long that uses Bristol Rd. There is a shoulder on Bristol Rd. for that section. But, you just don't want to be flying out onto Bristol Rd in a group. We'll probably have to have a ruling where nobody can pass or improve their position on Bristol Rd. Also, there are 3-4 speed bumps on the CB South access road that you should be aware of. They are the flatter/longer speed bumps...not the short/tall ones. Having said that, there is one speed bump that is short/tall but you can ride around it.
Also, there are a bunch of tight/technical turns (7 to be exact that are either 90 deg or close to it) that you should be aware of on the course. See the map, or better yet..go out and ride/drive the course.
Anyway, check it out..and if you're interested..email me. I think it would be a good interval workout for racers, or newbies who want to get used to riding in a pack and knowing what the pace of an actual Crit race is.
