If you plan on traveling the 80-odd miles from Kettering in Northamptonshire, to London St Pancras on Saturday 23 May 2009, you may want to think again.
Due to engineering work, this just-over 1 hour journey will be taking you a mammoth 18 hours and will include no less than seven changes, five bus journeys, a kip on a station floor and a trip on the London Underground.

Given this, it will literally be quicker to cycle, maybe even walk, into London on that day.
