I think it’s unbelievable that a pro at this level shares this information and testing feedback to the public and in all view of his competitors, big respect

I am quite surprised at the number of haters commenting about the testing;everything that’s wrong etc etc. The bottom line is this: the separation between The top 30-50 world class Ironman triathletes is razor thin. Lionel hasn’t won it yet.....he needs to close the gap. Is data going to be the end all answer? Probably not, but it’s certainly not going to hurt him. This stuff may also provide a confidence boost for him mentally when the race comes....he’s done this testing in the lab but wanted to do it on the actual course. Sure....it can all go down the tubes if he becomes undisciplined on race day. But the better he knows his body, the better he can tweak his strategy...pretty smart I’d say. The guy is human....relatable. He’s made boneheaded mistakes....it’s frustrating....but man I can’t help but root for him.

I do 320 watts for 2 minutes....soooo maybe in 7.3 shape?

"I would have been able to drink one more bottle for the rest of the race ... And I'm thirsty so stupid" Lionel Love your sence of humour. Good luck this year.

Looking at Kona results the past few years, Lionel you are right there man! Keep pushin

Really enjoy this content Talbot! I look forward to seeing how this training season progresses for Lionel and how the things learned from testing are implemented. Thanks for putting this out there for us to watch.

Awesome! Previous vid was sucha a high quality . Cant wait for this one

Loved this video! I get super pumped every time I watch Lionel.

Thank you for sharing, you're living a true dream my friend, what a chance on this earth. Good luck for your competitions this year.

Can't wait for the Run part. Epic series you Guys are doing

Always watch Lionel for inspiration &/or a good laugh. Talbot great work on the film & editing amazing content!

Good to see the work going into not blowing up in Kona again. Good luck this year Lionel! Thanks for the video TC - always good watches.

I absolutely LOVE this series. I also enjoyed the narration as I know you have insights to Lionel and Tim and Rinny and Gwen that their coaches probably don't even have. Thanks for bringing this to us fans.

These videos are very well done and are great motivation. Thanks to Lionel, Talbot, David, and Erin!

This is some Rocky IV, Ivan Drago shit right here. Haha

Got a good feeling for Lionel this year. Nice job TC on the video

Glad to see that you're taking the training to the next level!

Great content. Good series. Thank you for posting

16:40 Is such a Lionel Motivational moment ... Amazing keep it up !!!

Great to see this being done. Having a coach and a set nutrition plan is going to make a huge difference

Lionel is going to need a dart set for Christmas!

So interesting! Even me as an age grouper can just simply do this and extrapolate a nutrition plan! Love this stuff! Go team Lionel; lets put Jan under pressure!

Good work with the music, and the edit going along

Hahaha love this video Talbot. Thanks so much for sharing. The spongebob part was gold. And i think Lionel will make a great transition to darts once he puts Frodeno under pressure. 😄

"Ironman race pace is pretty slow". I wish my fast was your slow Lionel! Lots of support from the UK. You're an inspiration dude. #nolimits

Really good add to have your insight Talbot

Brilliant work.

Looking forward to this. Swim video was great.

Respect to David, pro dude 🙌

Great music in this series Talbot!

awesome content! well done!

Go, go!!! 💪

Love the vids Lionel

Come to frankfurt Lionel, every one is starting in challenge roth a week later... so the kona slotts are up for grabs this year at frankfurt

Vamos Lionellllll!

“Do you feel like you could win Kona this year?” Lionel- “Don’t effin piss me off!” 😂 this guy is great

Great Video 👍🏻

i'm looking forward to the new Dart series youtube channel!

AWESOME, YOU ARE TOP 👍👌👏👏👏👏.

Guess I will see you two at STG then 💪🏼❤️💥

Was that a little bit of Scottish Lionel? “That’s just great” 😂🏴󠁧󠁢󠁳󠁣󠁴󠁿

More Lionel post workout rants :D

i love the "do you think you will be able to win kona this year?"

Beast. The lion is fierce

This man is great. What a gift to sport! He could try an actor career after triathlon

Lionel / Talbot , again fantastic stuff. I think this is your best video not only of Lionel but of your triathlete series. Question - 4 lbs loss in 2 hrs is a lot. What is the theory around sodium ? What kind of sodium levels are in the Gatorade bottles you are drinking in the rides?

320 watts for 2 hours. See ya later. 😂😂

You should go to Roth!! It will be great!!

Ha!!! He is talking to his watch, like knight rider, first time i see that in reality. 8P ... :D

17:52 song is Ava Low - Casual Chic

I don't understand why those measurements make sense. Temperature and humidity are very different in October. Therefore heartrate will be much higher, which will increase the sweat rate. Wish you all the best, Lionel!

LMAO those poor toes!! Training for the Ironman the first thing that went was my cute feet. I feel like one day I cut half my toe off just trying to get rid of this corn I developed to paint what was left of my toenail lol.

Over thinking is lionels biggest mistake. I can relate to this guy. I’m the same

Interesting rewatching this video after the 2021 recap video that Lionel just now figured sodium is important to him. Wasn’t all of data obtained during this testing used?

What was the weight loss result for the second test? (And Lionel, from those of us fighting our own amateur battles with dehydration/hyponatremia, thanks for being one very fast canary in a coal mine!)

Lionel, Really appreciate all the effort. I suggest you get in touch with Dr Phil Maffetone, if you haven’t already. He was instrumental in Mark Allen’s success at Kona.

“Do you have any idea what Ironman...” Lionel- “I have exactly what idea..” “Can we make that public?” Lionel- “you can do whatever you want” 😂 spoken like only he can. I love this guy

"(This is sarcasm)" 😂

Gatorade wants your sweat rate information. I believe they are going to provide chemtrails for Kona 2020.

How relevant are the dat points for segments that don’t actually represent his physiological state following the swim? Likewise, he will run in a different physiological state following the bike and if this isn’t factored into his data points during the run testing, are they valid indicators of future performance?

Based on lactate, what are Lionels training zones?

I really hope there's a trip to a wind tunnel planned this year as another scientific "box to check" (and a video for it of course 😀👍).

Yo I'm gonna be at St. George this year too, except i'm hoping to push 225w for 5 hours, not 320

I would have thought the forearms wouldn't be such a great place to measure sweat as the arm is cooled by the wind? Guess not!

wow... so many lactate test may take LS to need a blood transfusion....

Hey lionel. What about coming to Germany this summer to race IM Frankfurt? You would be definitely cheered on by some crazy german fans. Think about it...

Hey Lionel,what pedals you using in the video pls?

Lies about zwift weight... I'm on to you ⚡🚴‍♂️

does sweat rate change over time or levels of exertion? If so, cutting up the course like this doesn't make sense. Please address this issue!

How do you determine your ability to take on stress and still perform at your fullest? I had just got back into tri this last year after a 10 year break. I noticed I'm not so anxious to jump into a bunch of races like I use to. Of course it's not my job where I need to bring home some bacon through prize money. But, it seems that there is some consensus that an individual only has a couple strong races in them a year. When are you recovering from the season? It appears you have a strong work ethic but could you be working too hard - too soon - too much?

What about the wind tunnel? He has to improve aerodinamics

his warm up is my 20min ftp test

Lionel, when are the Zwift national championship races?

What size LG helmet do you wear?

T.C "Look a little chubby" L.S "Mx" Lol

Did he have to do the 2h without consuming anything or did you took into account anything he ate/drank?

What is his race weight going to be?

Zwift weight lol

so casual: 2 hours at 320w.... :-)

Someone please tell me what those red sunglasses he’s wearing are

Any idea of his FTP?

SO NO ONE ELSE IS BOTHERED BY THE FACT THAT HE AINT WEARING HIS SEATBELT

What was with that random Josh Amberger impression?

Ever considered fat adaptation?

Stay safe will you? I am kinda worry seeing a clip of you riding with out any escort car. Cheer!!!

100% of the IM world champions never had a car accident while not having their seatbelt on ... You are putting so much efforts in this quest... Do not ruin everything for stupid things like this... Thanks for sharing and keep focusing... It will pay off !!

translated into Spanish, thanks

that cadence only looks like 85 to 80, maybe he should pace his cadence too, i find that helps me.

At some point, perhaps after a few more thousands of video filming hours, Talbot Cox may learn how to focus properly. For example to not rely on auto focus all the time, as when he - as often happens - misses a focus point it keeps the background tack sharp and the main subject(s) all out of focus despite them being at a fixed, predictable distance from his camera. Nah.

Every world tour rider goes through this sort of testing.... A LOT. its a thing, its real, gives real data for real program planning to give you the “marginal gain” ( as they call it) over the guys beating you on the last km or the last hour of racing. All the guys winning have this data and have a training plan based on it....If you guys dont get that then thats fine, but dont armchair-expert comment saying its bulshit, because it most def is not. World tour teams are not in the business of wasting money on thing that dont give the results, they spend a lot fo their budget on this data for a reason.

Wonder what he'll do if he wins.... I mean the last 3 to 4 years have been Kona Kona Kona.... what's next? Where's the real value? I understand he's a pro with obligations to win, but after watching all his videos, and I dont know him personally, I kinda feel sorry for him. Just seems everything is about Kona. I think I'd enjoy seeing him have some balance but what do I know?

(This is sarcasm)... Is it though? Lol

Add substitles please!!

Nothing to dissect here. no need to nuke this, stop overthinking this. It is the bike leg, RIDE AT YOUR POWER for the leg. One of your videos you mentioned how you chased Kienle and tried to hang with him. MISTAKES LIKE THIS are what cost you dearly RIDE YOUR POWER . . . RIDE YOUR RACE!!!!! STUPID HURTS . . . Trust me I know.

IS that meant to be an Aussie accent

The problem with Lionel is that every year he swings the pendulum in the polar opposite direction from the year before. How many times has he gone from self-coached to “I need a team of people around me!”.... Every time he drags other people onto his team, he either gets injured or turns up flat in Kona. The dude just needs to RACE rather than obsess over all this nonsense....

at my place we say: "The donkey only goes once on ice"

Control illusion, I'm afraid

Kill it

He raced his first Ironman in 2020. And is this really the first time he does these kind of tests to prepare himself for the upcoming season? Really? Every professional athlete who takes his training seriously does this at least once every year. Lionel has talent. No doubt about that. But his attitude doesn’t match up. And his ego prevents him from winning Kona. And with the new incredibly fast new athletes moving up from the 70.3 circuit, it will become really hard for him to ever stand on the top podium spot in Kona.
