Thanks all, sounds like I better get a-searching. Newhaven Dieppe might also be an option.
First Google results haven't been encouraging, and "Can I get early morning entry to the tunnel" returned a mixed bag of results, there's some strange people out there and no mistake...
Hi D, legs are doing ok thanks. Against all expectations I've kept my eye in, as it were, (for Gods sake, don't put "tunnel entry+eye in+whacking perinium" into Google, or the boys'll be round) and am planning (planning? PLANNING!! - cue maniacal laughter from the cellar) a round the clock Lands End to John-O-Groats sometime in May. I'm concerned it might finish me off though.
Mike, sounds good, I'll be in touch nearer the date mate.
Wahaay!
