Is Critical Power Taking Over FTP? (Functional Threshold Power)

RCA Head Cycling Coach Ryan Thomas recently discussed what FTP (Functional Threshold Power) actually is and how Critical Power is becoming more important in the cycling scene. This new form of measuring fitness by using critical power gives you a better understanding over your body and adaptations that are occurring. Will you be using Critical Power to gauge your next efforts?

one note about ftp: for non elites our ftp is not really 95% of the 20 mins max effort...but rather in the range of 85-90%. If I take it as 95% of my 20 mins max I know for a fact I can't keep that power over 1 hour, maybe 45 mins but not the whole hour. If I try on 90%ish it's more realistic, and ofc that depends on how well rested I am and how hard I trained that week.
Great info
Great chat Ryan! Always learning from you.
I've been looking forward to this video!
Very interesting stuff.
Great video. CP is a very neat concept. We have our students run a 3 minute all-out test in our exercise physiology labs. With CP and W' you can also predict how long the athlete would last working above CP. (based on a consistent power output above CP that is)
Hi Cam, you recently did some testing at different durations as part of your fast at 41 project. How about putting your numbers in to the High North calculator as a demo? I've just done this taking numbers from my power curve and it's confimed what I've suspected for a long time... that my anaerobic reserve is a pretty mediocre at approx 10 kJ.
I've been testing my CP this season using High North's protocols, but as mentioned FTP is still king on most training platforms so it's tough to do much with CP besides understand relative strengths.
How could you get critical power metrics on a headunit?
What determines the time to exhaustion@CP? Is it only the size of my carb storage since the body almost exlusively relies on carbs at a CP effort?
put whatever number you want against ftp or cp. the question is, in order to "improve" fitness, how hard do you ride, how long and how often. its a fine line between enough and too much. find your own balance and hang your ego at the door. as time goes on i'm riding more with power, guided by RPE.
Great video guys
XERT have been using this method for years
W' is an interesting concept but it leaves a bit to be desired. If i'm starting fresh, I have a W' of around 25kj. If I've already been riding at threshold for 10 minutes however, The reality is my W' has been blunted to around 15kj, even though I've done no work above threshold.
Something I always say to people is that with your workout sessions the intervals within the workout are meant to challenge you and it's OK to not hit all the prescribed intervals in a workout, if you have an all green workout chances are its too easy for you
I use Half Monty, done one 4DP and it was more stressful mentally than physically, and it's so difficult unsupervised to really know if you are starting at the right power, hitting peak and holding on to the limits of your 5/20 mins efforts. So- 64 million dollar question do Wahoo SYSTM plan to incorporate this or stick with HM/4DP???
This was great. I’ve been tracking W’ a couple years now.
With respect to training zones. Why is it that the zones of Strava are different from the ones given by the Wahoo app? I have tried to modify the Strava zones but the app doesn’t allow it. I have written to Strava asking for an answer to this discrepancy too, but I was told Strava follows “the protocol”. Why is no one talking about the different approaches you can have in workout zones. Is there a universal protocol for this and, if there is, why does Wahoo and Strava differ? Thanks!
Yeah most people skip the 5min to impress their friends with an overestimated ftp and later are surprised that sweetspot is hard. There are no shortcuts.
Look at those tan on the fingers 😅 good info. Thanks for sharing.
