Two years ago Boris kindly arranged a London skyride on my birthday which was thoughtful of him
I turned it in to a wiki meet and we had a picnic in the park event after the ride. I say after the ride but only two of us brought bikes & the rest just came for the picnic but we had a great time.
This years event is happening the day before the Ride London 100 so thinking of doing the same this year. The cycling is a bit manic but still fun.
