If any of you competitive types live near Richmond Park, you could try to beat the gauntlet laid down by the Bike Radar lot.
Seems they've been timing themselves over 3 laps and putting up the results.

I seem to remember some Addiscombe rider once describing how he was passing through Richmond Park after a very long ride one day, and getting involved in a "lap challenge" with some people only to wipe the floor with them. Probably someone like George.
