The 17:49 Virgin would require reservations whereas the two London Midland do not.
The Eastcoast website seems to think otherwise. Unless you mean bike reservations, of course. We weren't planning on bringing bikes, in our capacity as stokers.
Ride departure still planned for 10:30. Any issues with that?
I was going to say "sure, no problem", but I just checked and discovered that the local trains between here and New Street don't start early enough on a Sunday morning. We'll probably have to use a *shudder* bus (a subject on which I shall have to consult with barakta), or re-think the not-bringing-bikes approach (especially if Martin109's car is available for storage thereof).
Either way, I don't think a later start is going to improve anything, as we'll just get tighter for time at the end.
