Yebbut, facetious posts aside, a great deal of that planning kind of went out of the window when it was realised that 280m+ days throughout the summer are not sustainable. This was a lesson that had to be learnt, but, once learnt, Steve reined in his expectations of what can be achieved at best in the spring and summer months. Team Steve need to consider other reactive measures (besides the vehicle transfers which haven't yet materialised) to save this attempt. Miles' attempt was unsuccessful mostly because he did not put to his use the intelligence garnered by Kurt's, Steve's, and his own successes and failures.
I'm worried that Steve's going for an early start today; his track record shows that significantly increased mileage on one day is usually nullified by tougher subsequent days and ends up as a deficit when seen over a three- or four-day period. Kurt has had success with short circuits, with company, and with lightweight kit (all of which Team Steve could try), and with the recumbent and with warm weather (which are admittedly trickier to implement, or would take some considerable planning). To paraphrase the Walker Brothers, Steve needs to make it easy on himself, especially as he is adjusting to his new diet (which I would not question if it were considered by experts to be essential to his long-term health).
