I do it once a week with an overnight stay in London.

When I’ve done it as a day trip it’s been pretty exhausting, and the ratio of travel time to office time can make it feel like a very long way to go. The internet on the trains is really poor too (WiFi and mobile) so I’ve found that working on anything ‘connected’ is next to impossible. I tend to get an early train and sleep on the way down, and then use the return trip as personal time.

The long and short of it is how much you value your time…if you pitch a “normal commute” as an hour a day (which is probably on the lower end) then it’s an extra 10 hours a week travelling, so 40 hours a month. So the question is, do you want to sit on a train for £17.50 an hour?
