Steve has consistently said he'll do it his way, and no one can argue that he hasn't done that! But it became obvious in the summer that the mahoosive daily distances he'd planned on would not be consistently possible, even without weather, mopeds and bouts of sickness. The change of diet, however sensible prior to embarking on this challenge, really didn't help his daily distances - though it may well be that it was medically necessary.
The evidence suggest that Steve knows what he's doing - and that may be part of the problem. What he's doing is what he knows, and it's not working out how it needs to. If he can take up LWaB's offer, that could make a big difference - it's worked for Kurt.
