I joined the Flying Hairy Legs club, they are not a bad bunch. Pretty serious with what they do, I highly recommend them, they have a group site on yahoo I think.
Flying Hairy legs meet at 6h30 on Saturday at the Maglev metro station in Pudong for a 90 K ride towards the airport. B group leaves at 6h30 and rides about 30 km/h, faster A group leaves at 6h45.
Good group.
