Mikael Eriksson

Mikael is the Founder and Head Coach of Scientific Triathlon, which he started as a blog in 2015. He started out as a runner, and running was also his first focus once he got into coaching. But as his Mikael shifted his own athletic focus to triathlon, his coaching focus soon followed suit.
As an engineer, Mikael always had a great interest for science and understanding the mechanisms behind endurance performance. If we understand performance at a physiological and biomechanical level, training to improve performance becomes much easier.
However, Mikael strongly believes that the science of training or coaching is only one input to coaching decision-making. The other inputs include the athlete’s feedback and experience, as well as the coach’s anecdotal knowledge and experience.
Mikael enjoys the challenge of finding the balance of getting the biggest possible return-on-investment on training time. This requires carefully considering multiple inputs including the athlete's feedback, objectively measured training response and performance, factors external to training like work and family, and using these inputs to always try to improve training planning. Never believing you have the best answer is the key to keep improving.
More than anything, Mikael emphasises the importance of coach-athlete communication. Without great communication, a coaching relationship can never be fully successful. Triathlon is about so much more than just numbers in a training log. It's also about psychology, confidence, and even productivity and time management. And it is only through ongoing, open and honest conversations between the coach and the athlete that an athlete can reach their peak performance.
Mikael is at full capacity with age-group athletes, and is currently only taking on professionals or aspiring professionals as new athletes.

Personalized training adjusted to my routine, goals, and points for improvement
Mikael provides personalized training adjusted to my routine, goals, and most important points for improvement. Being coached by Mikael has been great. I've learned things like the importance of different types of training stimuli, I learned to do the easy training easy enough, and I also learned to consider the psychological aspects when racing.

Coaching has helped me a lot as an athlete and as a person
I was someone that always wanted to go hard all the time, but after I started training with Mikael, we introduced the concepts of consistency and going easy and hard in the right moments. This has helped me a lot as an athlete and also as a person. Coaching has kept me motivated, and the fact that I continue training today even under very difficult situations like moving countries, starting my own business, and the birth of my son is because I had Mikael with me during this journey, always caring and helping me to adapt to these situations with flexibility, empathy, and understanding.

I've loved my time training under Scientific Triathlon!
I started working with Mikael to find more consistency, and have someone to rein me in to avoid injury. Mikael and I worked very well together and have become good friends. I feel I can ask Mikael pretty much any question and be confident that I'll get a good answer. The training program is very thorough, customised to me, and clearly very well thought-through. In our ongoing communication, Mikael is always responsive and attentive. On top of all the quality training and performance improvements, I've learnt so much, adding further returns on my investment. It's been a blast!

Evidence-based and thoughtful coaching with objective and actionable feedback
What I've gained over the last two years being coached by Mikael has been daily evidence-based and thoughtful coaching, balancing performance aspirations, with the inevitable flexibility needed based on a life outside of sport. Equally important has been honest and respectful back-and-forth communication. This includes daily objective and actionable feedback to my training execution. I get detailed explanations on the "why" behind specific sessions. There is an abundance of open discussion. As an athlete I feel like I own the planning process by participating in it throughout the season.

Objectivity, knowledge, and long-term planning
The greatest benefits of being coached by Mikael have been the objectivity, knowledge, and long-term big picture view of planning and programming. Also, Mikael listens to and integrates feedback and thoughts of the athlete into the training. I've had many coaches and know even more. You go above and beyond all of them. Keep it up!

Training adjusted to life, great communication, and better results!
Mikael takes time to get to know not just my athletic goals but how those are seated among my professional and family roles. He helps me realistically adjust training when necessary, so I can relax and enjoy the training rather than spending my own time to create my own plan... and I’m getting better results! I appreciate every bit of positive feedback and teaching about how to do the workout better next time. Mikael’s prompt and clear communication is one of his greatest assets.

Breaking barriers previously thought of as unbreakable
Being coached by Mikael has been highly effective and beneficial, and has allowed me to break barriers previously thought of as unbreakable. The program has detailed and clear instructions, always paired with an explanation of the clear purpose, and the communication is fast, precise, honest and open.

I can trust the process and the program
Having someone with a lot of knowledge helping me towards my goals like Mikael makes me feel confident that I can trust the process and the program. This reduces a lot of stress I would otherwise have, planning the workouts myself. I also appreciate the very good communication.

James is an elite level triathlete racing on the ITU international Circuit. As such, he has competed among the world’s best at various Elite European and World Championships as a Junior, U23 and Senior. James has had the privilege train alongside some of the world's best athletes including the 2014 Commonwealth Champion, Olympians, IRONMAN Champions and ITU World Series medallists as part of his squad based in Loughborough.
In addition, he has been coached and mentored by some of the world’s best coaches. This has given him a unique insight into what it takes to become the best and experience of the best coaching practices, which gives him a great edge as the coach of performance-driven athletes.
James also excels at coaching athletes at the very beginner level. He has helped athletes that are just starting out in the sport progress rapidly and go from the couch to complete their first races in a short amount of time.
His pragmatic approach and excellent communication and athlete-centred coaching ensure that all of his athletes are in excellent hands.
Working at the East Midlands Regional Academy (part of the British Triathlon development pathway for talented junior and youth athletes) as well as leading and assisting with sessions at the Charnwood Triathlon Club, and Loughborough Students Triathlon Club, are experiences that have helped shape James as a coach and give him valuable in-person coaching experience.

There are no limits or barriers now that training is based on my abilities and science
James is a great coach. He has a deep knowledge and understanding of the sport. Being a top athlete himself he knows all the tricks of the trade and helps filter out what only works on Facebook and what actually works. And he has a great personality, is genuinely interested in his work and makes you feel like an old friend. It feels like there are no limits or barriers now that training is no longer shooting in the dark, but based on my abilities and science.

I feel really fortunate to have a great coach behind me
Three years ago I had never swum laps in a pool (since school days), never owned a bike (again since school), and was only running occasionally. And less than 1.5 years ago I was so fatigued I was napping during the day and could barely manage a slow 5 km run without my heart rate hitting 180 bpm. To think that now since being coached by James I'm feeling great, managing up to 14 hours of training a week, and am soon to attempt a 70.3 is just mindblowing. I feel really fortunate to have a great coach behind me. James' attention to detail in the day-to-day data, as well as his view of longer-term picture has been hugely beneficial to me, and I also really value the consistent communication and support, no matter the time of year or what's going on.

I have had the best year of training in my life!
Since I hired James as a coach I have had the best year of training in my life. I am now able to have bigger aspirations in the sport thanks to him. I couldn't have asked for more. Before getting James as a coach my fitness had plateaued since I was unable to train consistently. James taught me how to properly structure my training and approach it with "minimum effort for maximum adaptation". As a result, I have improved as an athlete and am enjoying triathlon more than ever.

Systematic fitness improvement and more confidence in the process
Being coached by James has helped me improve systematically, spend less time planning and worrying about training, and have more confidence in my training. I used to spend a lot of time preparing and worrying about my next training block, but now that I have James I just think about the execution of training. James can explain every step of the training and adapt it on a weekly basis, which leads to great confidence in the process and fitness improvements.

My training now has the structure I need to progress
Being coached by James is brilliant! He is a very good bloke who I wholeheartedly trust with my training to achieve my goals. With his help my training now has the structure I need to progress, I've learnt that less is more. I used to do a lot of junk miles and was not anywhere near as consistent as I am now.

Ready for an Ironman
Lachie is an excellent coach for me! I signed up to get ready for an Ironman, and the plan with great planning of workouts, effort levels, and periodization has got my fitness to a level where I feel that I am ready.

Invaluable advice, feedback, and improvement in all three disciplines!
Lachie has helped me improve in all sports, and I can see and understand the rationale of the plan. I had a coach before, but I find Lachie more experienced and his advice is invaluable. I'm always getting feedback on workouts and the fact that Lachie is a professional triathlete himself also generates some invaluable tips.

More focused, individualized training and better communication!
With coach Lachie I'm getting a training plan that is more focused around my individual circumstances and better communication (quick responses and independent follow-up) than with my previous coach, which is exactly what I was looking for from this coaching relationship.

Knowledge, purpose, and feedback
Coach Lachie is great! The greatest benefits are his knowledge and his ability to explain my training (i.e. the reason/purpose behind workouts), and I also like that fact that he knows what the workouts he gives me are supposed to "feel" like. Also, the feedback that Lachie gives me about most of my workouts in Training Peaks and our coaching calls have been invaluable to me as an athlete.

Consistency and accountability
I'm really enjoying the process of training and being coached with Lachie. The consistency and accountability it has brought to my training have helped me a lot as an athlete, and not having to think about exactly what I need to do in training is highly beneficial.

Exceeded my expectations!
Being coached by Lachie has exceeded my expectations! The plan is very personalised and high touch, and I have much more variety in training than before. Also, now I no longer have to spend hours researching training methods and session ideas, Lachie does it all for me and tailors the workout guidance and power and heart rate targets to me specifically.

Professional, personal and adaptable
Lachie's coaching is professional and feels like an exclusive and personal experience. He has helped me to remain injury-free and to really look at the long term goal and work towards that, which reduces stress from one-off bad days and the temptation of doing too hard workouts. Lachie adapts the program, volume and intensity to life circumstances like family and travel, and I've really benefited from the feedback on every workout and explanations about why we're doing a certain workout.

The best coach I've had so far in my triathlon career!
I've had several coaches before Lachie and this was the first time I felt like I had a professional, knowledgeable coach who also really cares about what I'm doing. I felt right from the start that Lachie knew what he was talking about and he explained why we were doing certain things. He also helped me lose the mentality of just doing more and more, and got me just as fit and strong on 4 hours less training per week. I was very happy with the communication too. We exchanged lots of texts and emails, and he was only too happy to chat on the phone if that's what I wanted.

Knowledge, communication, responsiveness and flexibility
I came at this coaching relationship with a strong desire to improve my knowledge and understanding of the sport, physiology, key performance metrics, use of equipment such as power meters, and Lachie's approach and guidance and support with respect to these is very solid, which has resulted in great improvement in my own knowledge and confidence. Lachie is also very responsive and communicative and he is happy to amend schedules at short notice, which is appreciated and pretty important when life regularly gets in the way of training.

Big investment but worth it!
Coaching is a big investment, but it's worth it. I love the program I get from Lachie, it is very flexible and it has helped me avoid overtraining and injury. You guys are awesome, glad to be working with you!

Extremely positive coaching experience with continued progress in all three disciplines!
Working with David has been an extremely positive coaching experience for me and helped me make continued progress in all three disciplines throughout the season. David is really great about talking about the plan for the next block of training along with the "why" and how it relates to the overall structure/goal for the season. He uses his knowledge, data and science, and the athlete's feedback to create a plan that works on the areas that will be most impactful for a particular athlete to improve. He's also always available if I have any questions.

"A completely different experience"
My coaching relationship with David is my second experience with remote coaching. My previous experience was called "individual coaching" but it was just a weekly training program coming from a workout database. Working with David is a completely different experience. David knows me and understands how I respond to training and how to manage my training load to avoid injuries and overtraining. He always wants to learn more and understand every detail that can help me improve as a runner. I've been working with David for about two years now, and am in it for the long haul, with the goal of eventually doing a full Ironman.
