well, strangely, to York for the FNRttC (and the recce). The Manchester to Blackpool FNRttC probably runs it close. I did once take a train to Jasper from Vancouver to cycle the Columbia Icefield Parkway - but that wasn't an 'event'
McShroom, Mikee, TC, JT and McWobble really shamed me in to looking for rides away from London.
