Wish I'd cyclocommuted this morning. Was busy sorting out my cycling gear before bed last night only for the wife to comment that I should get the train to be safe etc and I reluctantly agreed (silly me!).
Dry roads, no ice, no wind, nice and sunny - very nice cycling conditions.
You missed out.
It's very rarely that the weather stops me cycling.
Only 2 days in 2012 did the weather stop me cycling, that was due to the snow.
Like me you commute on the A21, apart from the bit near Catford Bus Garage where those dopey car cleaners throw water onto the road which can turn to ice. It's a very good, safe road to cycle on in any weather.
