As I pointed out back in February, using his home as a base, map out a couple of 40 mile loops, ride, home, eat and repeat. Do this through the Winter months and knock out the longer milage over the Summer cycling through the flatlands.
The thing here looking at both records is consistency in anything and everything. In terms of what you eat and what works, the amount of rest you get, riding time etc. Steve and his team need to think hard about what works for Steve and work from that and remember what record they are trying to break. FFS you are not trying to break the Tommy Godwin record - you are breaking the highest annual milage record which is recognised as being held by Tommy. A simple distinction yet confound in it's implication on strategy. Forget about what Tommy done and where Tommy went, that was then, this is now.
This is by far the main reason that Kurt has suceeded, that is because he has recognised what record he is trying to break. It matters not to him, that Tommy cycled here or there, the only thing that matters is MILES, and with this the easiest way to ride them and be supported through them. Hence riding on the flatlands and being supported by Alicia. And when not on the road riding close to his home in Ark'sas doing loop after loop. Steve could quite easily do this from his home in MK, yes it would be boring but so what? It worked for Kurt.
Personally I'd wait until Jan when Searvogel has finished to see what new record has been set, because (with exception) of a serious personal misfortune to himself he will break the record - which I said he would - back in Jan - because he simply recognised what needed to be done and looked at the easiest way of achieving this.
And from what I've seen, Steve's team need to do far more and recognise when he needs help. Don't let him ride 60 miles in seven hours into a headwind before he had that unfortunate incident and don't make him go on a new diet half way through a record attempt in the Winter.
Also it might be worth investing in a power meter, working out Steve's FTP and then working out the intensity of his rides using his power relative to his FTP. This will be far more consistent then using a HRM and would allow Steve to perhaps ride at a slightly higher power/speed whilst still keeping the intensity to that of an endurance ride.
