Bear in mind, I'm not that strong a rider anymore. My 60min FPT would be in the 300- 350w range only. And aerodynamics count big time when you start hitting 40kph+ . A 400w- 500w rider has a lot more to play with!
Tim, also your FTP is bloody amazing.... there are some pro tour riders that would kill for that! You should be racing JPT!
Agreed. At 62kg that is 4.84-5.65 w/kg. That puts you from middle of cat1, thru domestic pro to within touching distance of international pro (5.69). And like FarEast says, I`m sure there are many pros who are only 5.5 w/kg. And then given your age, not being rude, but with VO2 capacity declining from the age of about 35 (though the amount of reduction is reduced if you keep training) then you must be in the top 0.1% for your age. You could race masters with those figures and be competitive. Congrats.
