✅ I don’t coach by imposing. I coach by teaching.

Data shows us where you are. Consistency takes you where you want to go. And trust in both directions, is what makes it work.

Triathlon keeps evolving, so I do too. New science, new tech, same goal: Better Athletes who understand why they’re getting better, not just execute.

15+ years in, I’m the guy in your corner. Your goal is my goal.

I’m Sergio. Nice to meet you. 🔵 taken in Woodland Park, Colorado by @triserg

Nadie te dijo que 20 horas a la semana también se cobran en lo que no se ve. En las cenas que te perdiste. En las noches que llegaste demasiado cansado para estar presente. En la paciencia que tu pareja ya no tiene. Te inscribiste pensando que era ambición — pero a veces solo es una forma cara de pedir validación. Un 70.3 bien entrenado te da el 100% del atleta que quieres ser, sin pedirte tu vida completa a cambio. La meta no debería costarte todo lo demás. 🔥 Comenta REAL y te mando cómo estructuro un build de 70.3 que sí te deja vivir.

This one’s uncomfortable to post. But I am 💯 sure somebody needs to hear it. 🚨

Triathlon is one of the only sports where destroying your marriage, your finances, and your relationship with your kids gets rebranded as ‘commitment.’

I’ve coached athletes who were proud of the miles and ashamed of everything they missed to get them. That’s not dedication. That’s addiction wearing a finisher medal.

A good training plan doesn’t cost you your family. If yours is, it’s not the sport’s fault — it’s the coaching.

If this hit different — DM me “BALANCE,” let’s actually fix it

Comenta cuál de los 4 es tu punto más débil — te digo por dónde empezar 👇

Triathlon ain’t easy, and there are no immediate results in a sport that is comprised of three different disciplines. Athletes often times think that they can reach a goal in just one race or even a season. But as coaches, we usually have to break the news to them that that will not be the case.

Triathlon is a long game, a test of endurance both physically and mentally. It’s not just about excelling in one discipline, but mastering the art of swimming, cycling, and running together. It takes time, seasons, and often years to see significant improvements and achieve your goals.

Let’s take the example of our very own Coach @triserg , who has been in the world of triathlon for almost 10 years and is now in his 40s. Despite the challenges and setbacks he has faced along the way, Serg is having the best season of his athletic journey. He has stood on the podium in every one of his last four races and has just qualified for his sixth 70.3 World Championship.

Serg’s story is a testament to the power of perseverance, dedication, and never giving up on your dreams. It’s a reminder that age is just a number and that with hard work and passion, you can achieve incredible things in triathlon.

So, if you’re feeling discouraged or impatient with your progress, keep pushing forward. Remember that your breakthrough is coming. Stay consistent, stay focused, and trust the process. Triathlon is not a sprint, it’s a marathon. Keep training, keep improving, and one day you’ll reach the finish line of your goals.

If you’re looking for guidance and support on your triathlon journey, be sure to check out our coaching plans and our experienced roster of coaches. We’re here to help you achieve your goals and be the best triathlete you can be. Let’s do this together!

Let’s audit your gear bag real quick. 🎒💸

Compression socks for racing — feels pro, does almost nothing. A $500 aero helmet for your 40-minute sprint bike leg — saves you seconds, not minutes.

Bike gear like oversized pulleys saving 1w at most, feels almost like a scam, but hey looks cool!

Buy all ultra light carbon attachments saving 100gr? Just fix your body composition, and loose the extra pounds, you will smoke your competition in those hilly races

None of this is “wrong” to own. It’s wrong to buy before you’ve fixed the things that are actually free — your position, your consistency, your training.

Marginal gains only matter once you’ve already handled the major ones. Most of you skipped straight to marginal.

These things are a basic learning blocks on my 1:1 training. Real coaching real athletes, no BS.

You obsess over your FTP number, but ride a dirty chain, cross-chain every climb, and take 5 minutes to peel off a wetsuit. That’s not an athlete problem. That’s a mechanic and a stopwatch problem — and it’s costing you more time than another 10 watts of fitness ever will.

Clean your chain. Fix your chainline. Practice your transitions. This is the cheapest speed in the sport, and almost nobody’s doing it.

Stop throwing your money in the latest new gear, unless you want to be broke with flashy disc wheel to only getting dropped in the run, do yourself a favor and don’t be that guy.

If I hurt your ego, good! that means you know i am right and i no i don’t need you to like this post. I just want you to think about it and be honest with yourself and do something about it.

“When everything aligns!” A race I’ll never forget. I could caption a bunch of blah blah’s but honestly we get what we put on. Race day was a repeat of many days of monotonous and “boring” training days (boring from the point of view of consistent repetition) As I like to say to myself and my athletes “YOU HAVE TO LOVE THE JOURNEY MORE THAN THE DESTINATION” #triathlon #trilife #triatlon taken in Monterrey, Nuevo Leon, Mexico by @triserg

Your handlebars aren’t the problem.

You just don’t want to admit it’s the saddle.

Comment SADDLE and I’ll tell you exactly what to check before you buy your next one — width, cutout, nose length. Not what the bike shop tells you. What actually matters.

Don’t just train the swim, bike, and run. Train the fourth discipline too. Transitions. Fast transitions don’t happen by chance, they happen by repetition. #triathlon by @triserg
