Hi All,
I am fairly new to cycling (18 months) but have been working with a trainer since the start. This week I performed a Conconi Test on a Cardrigus Ergometer and I am having trouble correlating the results of the Ramp test with my Functional Threshold. Tomorrow I will be doing a 40kTT test on my bike with a powertap and a Cateye CS1000 indoor trainer. I am trying to work out what power I should aim at in order to pace myself (I have never done a 40kTT test before).
THe results of the Conconi, which I understand gives me my MAP are 523.5W at 159 bpm (HR). I currently weigh 77.8kg giving me 6.7W/kg at MAP. My max HR is 184bpm. My age is 37.
Trying to read as much as possible, it is my understanding that I should be aiming at 72% to 77% of MAP as being my FT.
This is where things go wrong for me. I should be between about 370W and 400W for FT. Yesterday I tried to correlate these outputs with RPE so that I can try to pace myself in the TT. My problem is I cannot maintain 370W for anything like 60minutes - closer to 5 - 10 minutes. From an RPE perspective I feel my FT is around 320W.
What is wrong with my logic?
1. As I have not been cycling very long, would be FT be significantly lower than the 72% - 77% range?
2. Can there be this much discrepency between Cardrigus and PowerTap?
3. Have I misunderstood the concepts of MAP and FT?
Any help would be much appreciated.
