@LMT: Correct in parts but I don't think that's an entirely accurate summary!
After hearing Idai stress a number of times that Steve does have a plan (and, note, that he plans to share it), I went back to examine Steve's original mileage schedule for the 1st Attempt, see:
http://oneyeartimetrial.org.uk/the-preparationFrom my calculations it does appear that
if he can stick to those planned mileages until 7 August 2016, he will have - just - surpassed Godwin and will be nip and tuck with Kurt's likely total. (I could be wrong - someone may wish to double check.)
That is a very big if, though. The proposed mileages for the summer months are enormous, exceeding what Godwin and Bennett were riding in their crazy summer of '39 when they had pacers, motorised support and may have been drafting lorries all along. With hindsight, it's odd that there were so few raised eyebrows at the schedule when Steve published it back in December 2014. His speeds thus far do not suggest that those summer mileages are possible, but then again, he's had terrible misfortunes and he evidently thinks he will ride himself into greater speeds, as originally planned.
One possibility is that the original schedule has been adapted, with Steve 'merely' matching Godwin through the summer, and riding closer to 200 mile averages in the winter and spring.
Either way, he'll have to do something that he's never done before, something neither Godwin or Kurt have done, but I suppose that's exactly what this whole record breaking business is all about.
