Hi there, I need some advice on how to adapt TR workouts…
I recently had a Physiology assessment at the Boardman performance centre in the UK (highly recommended) - they identified that I have the unusual capacity of being able to hold a high proportion of my VO2max for a long period of time - essentially my FTP is about 87% of my VO2 max power, where I believe around 80% is more normal. My 1 hour/FTP HR is also 90% of my max HR, which I believe is quite high too. I think this is giving me issues with VO2 max workouts as currently set up in TR as I am so close to my maximums at FTP that even 110% FTP blows me right through what I’m capable of sustaining for more than about 90 seconds. Basically almost any power level above FTP results in HR going out of control and legs blowing up. It’s not about gutting it out, I know VO2max workouts are supposed to be hard, it’s about bashing into limits where I end up involuntarily backing off as I am simply unable to pedal any more (as per the end of the ramp test).
Threshold and sweet spot workouts are not a problem so I am happy that my FTP is set about right, and I’ve done a recent ramp test to confirm this.
I’m trying to improve VO2Max and power at VO2max, so doing short power build at the moment, but I can’t successfully complete any intervals without knocking the intensity back to about 90%, and even then I will often really struggle with the longer intervals, longest I can really manage is 2 mins at this level. Know it’s about getting fitter and hopefully as I improve I will get further through them, but given my physiology is it logical to assume that I should be doing these intervals at 90% and at least getting close to completing them, or should I just bash on at 100% aand accept that I will keep blowing up?
Does anyone have any thoughts/advice?
