Got really tested on this one today.
Two walks of 30 min+ to/from Albert Bridge, the return one leaving me drenched.
Then, later at night, ride to Tooting for dinner, and again got thoroughly drenched on the way back.
Tomorrow, riding to Cambridge on the old faithful (my old Trek hybrid) with a heavy backpack. Hope the rain holds off at least till we cross M25.
Thanks to this sudden downturn in weather, this June challenge has suddenly become a lot more challenging :)
