Ramsey about 27 miles out but neither of these are concerns, I've had to collect my parents from as far out as Cambridge at that time in the past. As for the trains I wouldn't worry, I live about half hour from Huntingdon station which has a service to London kingsX every half hour (I think the fast non-stopper express is every hour). I think it's even faster and slightly cheaper than the Cambridge service as well.

As for early ups well, I've got to rise early to let the hens out anyway.
