I switched from Winter studded tyres back to Marathon+ a couple of days ago.
So although I am now riding the some of the slowest tyres in the world, I feel fast
My times for the commute reveal I am just going at a fairly normal speed
I think because I carried on riding through the snow I am fitter than some. For example on my commute there is a bloke on an old rusty Claud Butler riding the same route/time. Last year, it was a effort to catch him and on one occasion in Jan/Feb we had a real commuter race. He won.
Yesterday I saw him 200 metres ahead, caught him, passed at speed without pausing and didn't see him again.
I haven't seen the really fast guy on this route, mr Tarmac Specialized, he lives up Ford Street
