Had a very fast and easy run. First time I've finished with anything left in the tank. No debilitating cramp for once (really loaded up on salt on Saturday - I sweat it out to the extent that my cycling clothes get white patches). Had three strong coffees during the night, ate little, rode a light fixed gear.
If you saw me, I was in the St. Raphael kit on a blue Harry Quinn steel track bike the same age as me. What a machine. Was with two other chaps from work all the way.
The secret to not getting cold is to keep stops short. The air temperature doesn't make much difference if your clothes are damp with sweat - you cool off very quickly.
Fairly sure I saw you on route and possibly on the beach. We also made good time: built up speed after leaving Epping and pretty much kept the pace up until the finish (much to my suprise! I was sure I'd be spent by Sudbury). I was the stupidly tall guy riding 26" framed racing green Condor (1976 - a wee bit younger than me). My two pals were regular sized and on modern bikes.
