its probably been said before but I think they two (?three) modern attempts are actually very different so shouldn't really be classed as the same record... Florida is well known for its hills and bad weather where as the UK is flat as a pancake and mild even in winter...
Perhaps the UCA should have regional records? so the chap in Florida isn't beating the UK record he is setting the first Florida one using the distance set in the UK as a benchmark...
Go Steve though - incredible progress so far.
Similarly, it could be said that NEITHER of the modern record bids can be compared to the original Tommy Godwin record; thanks to modern lighter bikes with wider ranges of gears, better lights, improved clothing, etc..
The fact of the matter is that the record is purely for DISTANCE cycled in a year. It's not in any way related to height climbed, headwinds beaten, days of rain, or miles done in the dark.
If both Kurt and Steve are successful, then Steve will obviously still have the BRITISH record, irrespective of what Kurt does.
