London's just cold and damp at the moment, with hardly enough settled snow to make a decent snowball out of. However, guest blogger John T (right) has just sent us this report from an arctic-looking Hertfordshire...
Years ago I bought a set of Nokian tyres in preparation for a(nother) trip that didn't come to fruition. Today they saw service in the wilds of Hertfordshire.
The tyres have metal spikes so you find yourself looking for ice to cycle on. They are clattering and unwieldy on a clear road, but on snow, or preferably ice, they're excellent.
They should be too. They cost more than the bike they're on.
I enjoyed cycling past cars crawling up hills, or getting off to help push, then hopping back on the bike as carefree as I dared away from them.
The only down side is that the bike won't comfortably carry a child seat, so I haven't been able to share the delights of ice cycling with anyone else yet.
