I've done that before Mark, very doable to get to CSS in time. I just stuck the car at the top of the side road by the kwik-fit, it's free parking.
A 10 although a short race will be a full on effort though so may tire you more than you think so when I joined the CR after I dropped a group and used it to spin my legs out. Of course you could always tag on to George's wheel for his little session
