Got out for a cycle at lunch today...same route as I done on Tuesday but done it eight minutes faster. Most of that eight minutes was made up at a point where we had to stop on Tuesday to wait for one of the lads who'd got a phone call. I was a bit surprised by this, as I felt I was taking it a bit easier on Tuesday.
To that end, went back and had a look at my average speeds for some of my rides last year and was surprised to see a few of them were actually faster than todays ride. I think the main difference with them though was that they were done with other riders.
In any case, I'm very happy with my 27kmph average today...hopefully get that up over the next few weeks.
