How do you define "elite" ?
At 200 lbs for 6.1, your FTP would need to be over 3.5-4W/kg to make you an elite cyclist which puts you at an FTP of 360W. And let me tell you from my personal experience. Going from 150W to 250W is a lot easier than going from 250 to 350W of FTP at the same weight.
Much easier to lose 30-40 lbs to reduce "tonnage" as they say. At 72kg, FTP of 280W would put you at a highly competitive level.
Regardless, great ride, I hope you enjoyed it. Remember to hydrate and fuel at least every 30 minutes. Calories in, calories out.
