Chapter 1: What inspired the guest's journey from kayaking to hybrid athleticism?
Ivan Volt. Ivan Volt. Ivan Volt. Yeah. That's a strong name. Your story is an amazing one, and it came to our attention through the Untapped Athlete Challenge that we've been talking about. I think your first reaction to it when you saw one of the posts, I think somebody tagged you in it, or you came across one of our posts on Instagram, and I believe you said that they were rookie numbers.
We then looked into you, And you can bench 162 and a half kilos and run a 239 marathon all after fighting cancer and extensive chemotherapy. That to me, as soon as I saw you, I was like, we have to talk to this guy. Like those numbers alone are incredible feats of achievement. And they're so far ahead of, you know, the untapped athlete parameter.
um and you've got kind of both in the locker maybe not right now to to that level but i'd love to talk to you about that i believe that you could be our first okay untapped athlete and i'm really excited just to hear about i i thought where because you changed the name right it's and it's now an untapped athlete not my friends were starting to call me the apex well the apex you can have you whatever nickname you like i don't think legally we can use
I think it's more sarcastically meant speaking, right? But I was getting used to being the apex.
There's no reason for you to change it. In your own words, what are your greatest athletic achievements? So just for people who are unfamiliar with your story online, what are your biggest data points?
Yeah, so I'm not a runner, nor am I a lifter or like a strength athlete at all. I used to do kayaking professionally.
You're the only person I've ever met who's not a runner, who's run a 239 marathon and who can lift 162 kilos and not be a lifter.
239 marathon was my first first ever marathon. I've never ran competitively. But, you know, it's it's a side effect of what I've been doing as a kayaker, of course. And I have to put this out there as well, because I think that if you're looking for a sport with the most apex athletes or untapped athletes, I promise you it's kayaking and I'll back it up.
Guys. Order a kayak!

Chapter 2: How did cancer impact the guest's athletic performance?
So that's what we're working on. And asking me about my achievements, I am, I became European champion. So I have that in my belt. Kayaking? Kayaking, kayaking, yeah. And I have four, four world championship medals, bronze medals though. Yeah. But I did pretty well. There's a long story to it.
Can you just, for the layman, just explain what a kayaking event is? What distance do you cover? Are you a sprinter? Are they more long distance? What is it?
Yeah. So I usually perform best on the long distance, 5,000 meter. I even did pretty well on the 30 kilometer distance.
30 kilometer?
Yes.
Kayaking?
yes this is this is this is both both sides you're not you're not in a boat with other people not a canoe but you can do crew like i used to race together with my brother um who's um also i think he has a more uh in more inspiring story than me we can get into it if if you like yeah um Yeah.
So, so you do the Olympic disciplines or the world championship disciplines is everything from 200 meter to 30 K. Okay. And I was pretty versatile. So, so I, I was pretty fast and I was brilliant and joint. Uh, so I could, um, and even in the long distance, you have to sprint at the end and position yourself in the start. So it's, it needs a lot of explosive power.
What sort of heart rate zone do you find you would be in over the course of a 5K kayak? I'm trying to figure out how similar to running it is.

Chapter 3: What unique training methods does the guest use for endurance?
Obviously, it's a completely different thing, I understand. But would you be in thresholds for much of that? Or are you kind of zone three and it's more of a physical workout, upper body workout?
Where does your heart rate go to?
Yeah.
so you would be at max heart rate uh like but a little bit up and down so running if you're running a 5k you would sort of pace it to your average pace from the beginning right yeah with kayaking especially if it's a mass start like if you're doing just um um the 5k alone you you'd pace it on your threshold right or like your average pace but with a mass start you just have to go all out from the beginning like
full. And so you build up a lot of lactate just the first minute, like a lot, like let's say 20 millimole after a couple of minutes, which is a lot of people would just, they wouldn't be able to stand with the 20 millimole, right?
How long does a 5K in a kayak take? About 20 minutes. So similar to an okay runner? I suppose. So you're traveling pretty fast in the kayak. Yeah. Yeah. Yeah. You're doing four minute kilometers in the kayak.
Yeah. Yeah.
It's absolutely insane, isn't it?
But even like a thousand meter, you could do like the world record is maybe 320 for a thousand meter.

Chapter 4: How does the guest balance strength training with endurance sports?
And he was talking about lactic buildup and how to deal with it best, because obviously over the 800 meters, it's quite intense. from the very beginning. And it's not quite a max effort and there is some strategy to it, but it is largely to do with how your body processes oxygen. So you would have had, and probably still do have a huge VO2 max. And you need that as a runner as well, as you know.
So you're so conditioned to kayaking, which of course is monster strain, cardiovascular strain, but also great use of oxygen, lactic acid buildup, and the ability to handle lactic acid in your muscles whilst continuing to push into threshold. Obviously a big muscular load as well. And then you find yourself in a gym and you can just bench 162 kilos.
So are you saying that you don't regularly go to the gym and lift weights or bench press? So you wouldn't be bench pressing like three times a week consistently?
No, I wouldn't, but we would train a lot of persistent training with the kayaking and Depending on what distance you're focusing on, right? There are sprinters, 200 meter guys that can lift. I know a lot of these guys, they lift more than 200 kilos in the bench press, right? They can do pull ups with 100 kilos between their legs. Who the fuck are these people? Yeah, I'll show you some pictures.
Can they run a sub 250 marathon? My guess is no.
Okay. Order's been restored to the studio.
They can't. I think like combination, endurance, strength, I think even in the kayaking world, I would be pretty good.
This episode is brought to you by Yeoman, the new autobiography from the founder of Yeosushi, Simon Woodruff. On this show, we talk a lot about unlocking your potential and backing yourself to go further. Yeoman is that same story, a brutally honest, wildly entertaining account of how it all happened. Here's a story you probably don't know.
Before Dragon's Den, Simon Woodruff had been expelled from school, arrested for drugs at 19, and done time in a young offender's prison. He spent two decades as a rock and roll roadie, designed stages for major rock acts, and even worked on Live Aid.

Chapter 5: What are the differences between kayaking and running in terms of training?
By his early 40s, he'd been through business failures, a divorce, and was very nearly broke. Then at 45, with £200,000 and a mad idea about a conveyor belt sushi restaurant, he took a chance. Nobody came for the first two weeks. By week three, there was a queue around the block that lasted three years.
If you've ever wondered whether it's too late or whether it's even possible, this book is for you. Yo Man, out now on audiobook, ebook, and in hardback. I've never heard of anyone who can do a pull-up with 100 kgs on them. Yeah, yeah. Repping pull-ups or just one pull-up? No, that's probably one. That's probably one. Did you know that the majority of men can't do one pull-up? Did you know that?
I didn't.
No, no, no, genuinely. I think that we should find it as well. I think that it's only something like... Uh, it's like, it's something crazy. Like one in 50,000 men can do 10 proper pull-ups or something like that. Like genuinely, can we chat GPT that?
Not that chat GPT is the be all and end all, but can somebody find out like it's to be able to do a pull-up, we should add a pull-up to the, to the.
Maybe you should, maybe you should. 70% of men can't.
So only 30%. Do one pull-up. Do one pull-up. Yeah. Only 30% of men can do one pull-up with no weight.
Yeah.
Hmm.

Chapter 6: How does the guest manage their training schedule around a full-time job?
That 100 kilo thing is a joke. And they can run 100 meters in what?
I don't know.
I don't know about 200 meters.
But they're not awful, you know, with endurance because they still have to do a lot of aerobic work. You know, just to get the water feeling, you have to do aerobic work. It's not like, you know, sprint runners. Yeah. They... My impression is that they can't even walk to the office because they'll ruin their explosive fibers. So it's not like that.
They still have some aerobic base, even if they're really explosive and strong.
So would these guys look at you and think you're weak?
It's different qualities, right? I have the combination. My endurance is a lot stronger than the sprinters, right? And and even the 200K, you know, it's extreme. I'm not saying that everyone can do it, but I think there's a deviation. It's like it's a high percentage of of epic athletes or the combination of strength and endurance. You find a lot of them in the sport of kayaking.
I tons of friends that have been
noticing your challenge and like, yeah, he can do it, he can do it, he can do it.

Chapter 7: What lessons did the guest learn about mental resilience through their experiences?
I tried to prepare well, but The approach to training for running, you have to be so much more careful because you get so easily injured. You can't put in the hours like you do in other sports that I'm familiar with, like kayaking or skiing. So you have to be careful. I injured myself, so I didn't run much before then. Maybe I put in some long runs, like a month before New York.
So I did 244 and then... I surprised myself. I didn't expect to be that fast. So a few weeks later, I ran Valencia, which is a fast track, right? And I did 2.39. So I was pretty happy with that. And all of that was within the same year as, you know, being in hospital with heavy, heavy chemo, getting back my hair and doing the bench press and everything. It's... It's a crazy story in many ways.
And I'm sure you have other questions as well. But if you want, we can get deeper into it because it's a really inspiring story.
Well, I'd love to hear it, of course. Just quickly before we... Would you say that your level of hybrid athleticism with your strength and your stamina across long distance... Do you think it's very rare? Do you believe that you would be very competitive as one of the world's best hybrid athletes or not?
Yes, I do know that it's rare. Yeah, I do know. You know, the sport that I've really been dedicating myself to is kayaking, although I was pretty good in kayaking.
It's also very technical. I'm going to start kayaking, by the way.
So you watch out. But maybe I'm even better in this hybrid athlete thing, even though I haven't really...
I'm not comparing us as athletes because you're in a different league to me, but I ran a 2.57 in Tokyo on also not much training. I've only ever done six, seven weeks of a block.

Chapter 8: What future goals does the guest have for their athletic journey?
And you hear of people who do six, seven months. That's what we all say. We all say, yeah, we weren't prepared. No, no, no. I'm not saying I wasn't prepared. I tried for that time. But I'm just saying, I'd be interested in what a six or seven month training block looked like for me, but I'd be even more interested to know what that looks like for you, right?
Because you've done a 2.39 in this big bench on no real prep, really. You said you prepared for like a month, right? That's nothing. Like most people wouldn't see a month as enough time to train for anything.
Yes, specific running, right? But I still did a lot of paddling and kayaking.
Okay.
Yeah. I was about to say paddle boarding's surely not... No. Yeah, because like, you know... I did a lot of kayaking and also a lot of the Norwegians at least, they do for cross training during winter, winter training, right?
Cross country ski.
Yes. And it's... We need to just... It's a really, really good... like building the foundation it's a really good aerobic exercise let's hear your let's go deeper into your story right okay yeah yeah so um um yeah okay let's let's take it from from the beginning so i am um i'm uh i i grew up with um two brothers i'm the middle so my older brother he's um Have you heard of Norseman? Yeah.
You know about it? I know what Norseman is, yeah. Yeah, so some people, they say it's like the toughest triathlon or the toughest Ironman.
It's an Ironman, but it's in far harsher conditions, right? Harsher conditions and up a mountain, like a steep mountain. You jump off the boat to begin with.
