I could never do this, I lack both the mental and physical ability. But if I could, my strategy would be:
I would be UK based - I love cycling in Britain
I would never, ever ride into wind
I would have full time camper van support, this would transfer me downwind. Van would have a fixed bed for instant rest.
I would have full time support and would meet them at no more than 50 mile intervals
I'd use regular (daily) sports massages etc
Bike would be light weight carbon with minimal weight additions - wouldn't need much as would meet support every 3ish hours
I'd want every turn of the pedal to give max benefit - therefore minimal climbing - never more than 1000ft per 100 miles.
I'd publish my intended route based on forecast wind and invite experienced people to come and draft me - I like company too.
Daytime breaks would be minimum time possible - I like my 8 hours sleep so would want sustainable meals all ready to go when I stopped and then have as long off the bike as possible at night
I'd target the record plus a few miles - I don't think large increases are feasible
Finally, my crew chief would be as easy on the eye as Alicia and not have a face like a stunt man's knee!!!!
