Ready to get fitter and race faster?

Scientific Triathlon is all about helping age-group triathletes train smarter and achieve their triathlon goals. 

You've found the right place if you want to: 

  • Get started in triathlon without feeling overwhelmed
  • Improve your swim, bike and run fitness and race faster or go longer
  • Achieve great overall health and well-being by managing your nutrition and recovery, and by finding a good balance between training and other obligations

Hi, I'm Mikael, the face behind Scientific Triathlon! 

My goal with Scientific Triathlon is to give you the tools and resources you need to reach your triathlon goals, big or small. Whether you want to use triathlon as a vehicle to get in shape and lose weight, or you want to win your age group in a competitive race, the content you'll find on this website (including the Blog and the Show) and in the emails I send can help.

You'll find tons of valuable information on how to train smart using and with structure to get the most bang for your training buck, how to avoid injury and overtraining to be able to train consistently without setbacks, how to avoid stagnation and break through performance plateaus, how to manage your training and balance it with your family and work commitments, and lots more.

These are just some of the challenges that age-group triathletes face, and my hope is that the actionable and comprehensive content on Scientific Triathlon can help you overcome these challenges. Just like it has helped people like Andrew and Barry:

I am going to write my training plan for the upcoming year, and was looking for core training and a scientific approach to overall training. This was the twelfth site I visited in my search and it's the only one I use. Keep at it Mikael!

What you have written makes a great deal of sense to me. I like that you suggest simplicity in the early stages of the program. I have spent some time on your site and am finding so much of it makes sense! I am VERY impressed by the amount of care and work you put into providing so much information and guidance to your viewership!

By the way, if you're pretty new to triathlon, the right place to start is definitely the free, 3-part email course on building your own, personalized triathlon training program to get started. That's what Barry did, and what many other beginner triathletes have done with great results.

Whatever your experience level, the Scientific Triathlon Newsletter is the place to be. I save some of my tips and articles exclusively for subscribers, so make sure to subscribe at the bottom of this page. The feedback I've been getting from this exclusive group of readers has been amazing, so you definitely want to jump on the chance to get access to this additional resource.


What makes Scientific Triathlon stand out among other triathlon sites is the quality of the content. You won't find many 500-word articles here. When I cover a topic, I do it properly. The reason for this is that I don't want you to just consume the content here and forget about it five minutes later. I want you to really be able to apply the things you learn in your triathlon training, so the content is designed to give you the complete picture, but still be actionable and comprehensive. 

What a great concept for a website! I like how comprehensive and in-depth the articles are. Mainstream triathlon media don't offer anything like that.


My articles have also been featured in many popular triathlon magazines and media outlets like Triradar, Beginner Triathlete, and others.

Finally, I just want to say that Scientific Triathlon is not about me, it's about you. If there's any topic you think I should cover in one way or another, let me know right away. Some of the most valuable content around here has resulted directly from reader feedback.

Thank you for being a Scientific Triathlon reader. I look forward to getting to know you! 

Mikael Eriksson Triathlon Coach

About Mikael

My name is Mikael Eriksson, and I live in Helsinki, Finland. I'm an ambitious age-group triathlete and an ITCA-certified triathlon coach. I coach runners, triathletes, and swim-runners. By day, I work as an engineer (hence the love for a scientific approach to training and the name Scientific Triathlon).

I've been an endurance sports fanatic for many years, with road running being my main focus for a long time. Unfortunately, I got injured from trying to push myself to faster and faster times, and the injury turned out to be quite persistent. I realized that I didn't want to just lose all the endurance I had built up, and took up swimming and cycling in April 2015.

I had some very minimal road cycling experience at that point. As for swimming, although I could probably have gone the distance for a 1500 m swim, I had absolutely no technical ability and was horribly slow.

Luckily, I made a really good decision right from the start and immediately started working privately with a swim coach. She helped me to constantly improve my swimming and get faster, and even though my swim is still a work in progress her guidance accelerated the learning curve massively. 

I had a couple of good results within months of starting training for triathlons, even after a long time of no running outside of triathlon races. It was all very encouraging!

I trained really well throughout the fall of 2015 and winter and spring of 2016 to set me up for my big goal - the Sprint Distance National Championships. Sprinting my way to a top-10 finish was satisfying, but I wanted more. So to help me on my journey, I decided to do a repeat of the excellent decision that helped me so much when I learned how to swim: get a coach.

I am now coached by Simon Brierley, and I can't even begin to tell how great that has been for me. In the relatively short time that we've been working together, I've seen massive improvements in my fitness, race results (I realised a lifelong goal of placing on the podium in a national championship in the Duathlon nationals), and in my overall approach to triathlon. My goal now is to be a genuine contender for podium finishes in the sprint and Olympic distance nationals in 2017. 

Scientific Triathlon is my passion project. It's where I share what I've learned and am still learning every single day to help you be a better triathlete.

One of the greatest things about having a passion project like Scientific Triathlon is to get the opportunity to interact with readers like you. So don't hesitate to send me an email anytime to discuss triathlon, ask questions, or give me feedback. I do respond to every single email I get!
