As previously mentioned the "sportive" the South Western Road Club are running this Sunday is fully booked.
Richard can't make it now so his place is up for grabs. I've heard nothing yet so let me know if you want the place and I'll give you Richard's number.
It's 100km with over 1,250m of climbing and the weather forecast is good, full details at link in the sportives section of the forum. I can offer a lift from Croydon area.
Cheers,
Andrew.
