Definitely chilly - though not as chilly as previous editions, by many accounts. My garmin upload shows an "average of 0.6 degrees C" - on or below freezing until Kintbury.
Rode for a bit with a chap on the noisiest bike - an old Dawes(?) with rattling mudguards. Sorry, didn't get and/or remember your name - but thanks for the company! We got held up just before the Hatchet Inn by a flock of sheep (accompanied, luckily - not out on their own), which ate into the coffee and biscuit time. Then headed out alone, as he'd set off. Something I'd said?
A great day's ride with beatiful views - those climbs were worth every bit of effort. Thanks to all those involved in organising it.
