Nice set of data and explanations Dan. Good luck moving forward with your Ironman Wales training.

[@TriathlonDan]

Thanks Shane :)

[@alwaystmoza]

Great informative video, but did i miss something? Re your heading? Thought you would have also explained what others have been doing wrong in their test and why your method is the right way???

[@andrewhorsfall-turner5484]

What about LT3 🤷🏽‍♂️

[@tomoosterdijk]

LT3 all day all night

[@TriathlonDan]

LT3 isn’t ready for me

[@CoachPursuit]

Enjoyed this one Dan, love the data. Wouldn't mind getting data like this for myself!

[@TriathlonDan]

Go for it dude!

[@michaelgraycycling]

Enjoyed this. Getting a coach myself which will include lactate testing

[@TriathlonDan]

Nice one! The most important thing is just to ride your bike LOTS 😬💪

[@jamesfarndon9682]

Loved that great video. Pretty please can you do a review video for the aeroad vs the ultimate please. I think you have both. I’m torn between what one to get when the comeback into stock

[@TriathlonDan]

Thanks James! Funny you should say that, I have debated that for a while. Think I’ll do them separate though. I have an Endurace but they’re very similar to the ultimate really

Great video Dan - love all that data!

Cheers Neil, it just all needs to go UP now 😬👍

Lt2 at 144 HR. When I got a test done my LT2 was 178 HR is lower or higher better? I’m also curious about blood lactate. Your test show 305 watts at 2.10 mM/L. When I was doing research between 1.7 and 1.9 mM/L is considered zone 2 blood lactate range. So In theory you should be able to hold between 280 and 295 watts which is above your LT1. Right?

[@TriathlonDan]

HR level doesn't really matter if it's higher or lower, it's all relative to your own zones. I'm really finding the level I can hold vs other people varies wildly, even people with similar LT1 / 2, I do tend to ride 70.3 triathlon bike splits circa 285w and run well off it so it just re-assures me that's well below LT2, when I'm fit anyway!

[@adamshaw4652]

Top work mate, very interesting

[@TriathlonDan]

Cheers buddy!

[@ckuka]

Thanks for the very informative video. I think, you’re mixing things a little bit up. Your VO2max is in Competition Club level, while your MAP is in Elite Level. Your power zones are actually defined by this test. Until you don’t test, you had to create power zones by arbitrary tests like 20min*0.95 etc. Now, as you’ve three well measured thresholds, you’re able to determine the real power zones. LT1 defines the border between Zone 2 and 3, LT2+-~5% defined your Zone 4. Your MAP is the top end of zone 5. Your FTP should roughly equal your LT2. Please correct me if I’m completely wrong. Great video anyway!

[@TriathlonDan]

Thanks Chrisophe, appreciate that 👍👍

What we're talking about when discussing this is mitochondrial efficiency. The wording that still tends to be used gives the wrong impression of switching between fuel sources, when in reality you have to think of the mitochondria (in skeletal muscles in particular) as being an always on engine and the glycolytic flux as being a turbo which ramps up as the engine is maxed out. What I rarely see mentioned - and is in effect the difference between elite and non-elite athletes - is lactate utilisation, intramuscular shuttling, and mitochondrial lactate utilisation via mct1 transport. This is what keeps blood lactate levels low at higher O2 utilisation in highly trained athletes, the ability of slow twitch muscles to utilise lactate produced by fast twitch muscles without it entering the blood stream. It's trainable within a range of inherited limitations, particularly with Z1/Z2 training. This has been studied more in pro cyclists - Inogo Millan with Pogacar & UAE. It's why pro-cycing training is inheriently dull, and by extension IM training and why many train at too high an intensity. You should be - for the base and build phases - be training predominantly at upper Z1/low-mid Z2. It goes against the HIIT and sweet-spot methodologies which are really quick fixies to get a VO2max boost which then quicky plateaus. I mentioned Millan - this is a useful watch: kzbin.info/www/bejne/Y2ezdXWMh9B2gcU. My background is metabolic biochemistry.

[@stephenbetley9596]

Listening to their recommendations I don't particularly agree. What's needed for a hilly course is the ability to recover between harder intervals, and for this what is needed is a highly efficient engine with the ability to re-utilise intramuscular lactate - and by inference reduce fatigue caused by H+ production. My take, anyway. I'll tell you if it worked when I've done IM UK in July. :)

Ive been doing it all wrong! LT3 all the way ! #triathlonmockery 😝😝 great vid Dan keep it up 👍👍

[@TriathlonDan]

Haha love LT3

Great video Dan. I’m just looking at the courses at Loughborough. Which one was this that you did as they do a few. Was it Two Physiology Bike or Triathlon or the Cycling Physiology one (the cheaper one). [Edit] And now I’ve seen there’s one for fuel utilisation - confused. Cheers.

[@TriathlonDan]

Thanks :), I did the cycling physiology and body composition but I haven’t put a video up about that yet

I'm not that geeky to be interested in this (serious) stuff but if you do chicken's LT test I'll be first to watch. 🐔And that's constructive comment. 😂
