for those of you planning on doing the hairshirt, i recommend you come out with me and do 200km brevet ride as a training run. The "Bewdley Glutebuster" goes from Markham out to north of Oshawa and to the tip of Rice lake and back. it's a hilly route and lives up to its name, but it'll get you ready for a double century for sure. let me know if you're interested in details.
