That's probably as good a picture of Jan as was taken on the ride, for some odd reason there was always some bloke cycling just in front of her.
I agree with Teethgrinder about the temperature making things harder (although I don't subscribe to his practice of making 30 mile rides into 200 mile rides!) Even on my relatively short commute into work, when the weathers cold, it is distinctly harder to pull away fast at junctions, almost as though your legs have seized up a bit! I was also quite happy to get home after doing 55 miles or so yesterday, which was more than enough in that weather, and I definitely needed a cup of coffee when I got in, to replenish some of the heat and energy.
I was also amused reading Teethgrinder's ride report, that he left at 1-30am and got back at 1-30am, so did a 24 hour ride, whereas I almost exactly left at 7am and got back at 7pm, so did a mere 12 hour ride (I suspect many others had times similar to mine).
