Hmm... 53 miles, 11 a.m. start. This will be 5 hours' riding time. 2 hours' stops. I've got an evening appointment at 8 p.m...
You are going round your published route in an anti-clockwise direction, aren't you?
Sorry to be a pain, but I like to calculate fairly exactly what I'm up to.
Actually, looking at the Nat Rail website, that works out fairly well if I get a cheap day return from Rayleigh. Stupid thing is my Network Card doesn't get me a discount on that train if I get on a Prittlewell at 9.48 because it's before 10.00. If I get on at Rayleigh, where it's due in at 10, I do get the discount. It's a 7 mile ride to Rayleigh to save me £6. That train gets me to Manningtree at 10.58.
Rayleigh is also the nearest station to my 8 p.m. appointment.
If we look as though we are running late, do you mind if I dip out at Bures on the way back and make for Marks Tey?
