I've just been counting up the numbers, and it's likely to be around 21 of us in total, so with that large a group, it will slow things up a bit, so I reckon we'll finish around 7 pm. I've got the ride ending at St Pancras station, simply because it then makes it easy for me to get back home! I'll point out the side road you'll need to take for a quiet route back to Euston station, for Birmingham trains (or you can then carry along Marylebone Road towards Marylebone station for cheaper, but slower trains).
The lunch stop is at
The Lilley Arms which is after 41 miles, in Lilley. Although there are some nice pubs a bit before then, they would have been immediately before a steep hill, which I thought would be a bit cruel to inflict on everyone. As the lunch stop is past the halfway point, I don't reckon we'll be there until after 1.30 pm, so please can everyone ensure they've had a decent breakfast, and topped up their food levels by having something to eat before we set off. There is a small cafe in Northampton station for anyone arriving early by train, and we'll be meeting up outside the station entrance, aiming to leave by 10.30.
