Its not all about 3rds and 2nds cats? I've ridden all the main crits in London and at 4th Cat level I think this is the best place to start.
It all gets going on April 10th and runs through to August 23rd. So whether you just want to supplement time trial or cyclosportiv training instead of simply being a hardcore racer Hillingdon is a great place to start. If you can keep up with a GENUINE 19mph group you're ready. Make it an Addiscombe party all summer long. You never know you may even get to see Super Guru Ajay if baby Prya lets him come out an play.
