8 Tips on How to Train Smart for Your First IRON MAN Triathlon

 In Fitness, Uncategorized

Six-time champion IRON MAN triathlete Mark Allen and author of ‘Fit Soul, Fit Body’, shares tips on how to train smart and avoid injuries before and during the race

The IRON MAN triathlon is the ultimate endurance race. It starts with a 2.4-mile swim, a 112-mile cycle and it ends with a 26.2-mile run. That makes a whopping 140 miles to be completed in 16 hours! Gruelling, daunting but certainly not out of reach!

I had the privilege of speaking to six-time IRON MAN champion triathlete Mark Allen to get some useful tips on how you can get your mind and body ready for one of the most gruelling races of your life.

Start Right to Finish Right

The secret ingredient lies in the preparation.


Most of us beginners start out going hard. We push ourselves to run a full marathon, cycle endless miles and swim hundreds of laps in a pool if we can manage it but let’s put things into perspective.

By pushing yourself too hard, you might end up injured, fatigued or completely burned when we you are only just getting warmed up (no pun intended). Sincerest apologies Jane Fonda but “Feeling the burn” and “No pain, no gain” are somewhat dated philosophies and do not quite apply to the preparation for an IRON MAN triathlon. You may want to leave your ego at the door if you are serious about achieving this amazing feat.

Be a Tortoise and not a Hare


Humans are built for endurance rather than speed. Our ancestors never had to go hard or go home after every workout yet their bodies were strong, fuel efficient and healthy.

Start by slowly and gradually building up your strong aerobic (cardiovascular) fitness base or stamina. To understand your body’s optimum fat burning zone and stay within it during training, it may be worthwhile investing in a heart rate monitor. A heart rate monitor will enable you to regulate your training intensity according to specific demands of the sport.

As any triathlon is a test of endurance rather than speed, power, strength or flexibility, building up cardiovascular fitness/ endurance should be the building blocks of any beginner’s overall training programme.

Mark also mentioned that when doing low endurance efforts, your heart rate should not exceed 180-your age.

In the initial phase of the cardiovascular activity, it is typical for a beginner to observe his or her heart rate climbing beyond that limit early into the activity even though he or she feels they can go harder and faster. The reason why you should limit your heart rate during low endurance efforts is to strengthen and condition the heart muscle to a point where it serves as an engine to facilitate the body’s ability to be more efficient at burning fat and using fat as a source of fuel for the activity.

Focus on the Process Instead of the Destination

Aerobic training stresses the body less compared to high intensity training but this does not mean it should be taken lightly. Training is not entertainment but a commitment to dedicated effort.

In Mark’s book, ‘Fit Soul, Fit Body’, he stresses on the importance of slowing down to get faster. Every serious aerobic training session improves the body’s ability to breakdown fat for fuel and teaches it to go faster over a longer period of time.

Building aerobic fitness on a deep level requires some serious consistency and discipline. Training smart also encompasses self-love in that we should never neglect our psychological wellbeing in our preparation. An unhealthy mind would probably get us injured and result in burnout so we must be able to set aside time to recharge so we can come back stronger.

We need to gradually and patiently build up this aerobic fitness base so we can taper off just before competition and perform at our peak during the event. Do not overstress your body. Lower your expectations if necessary. Do not over race. Do not over train. Take your “active rest” very seriously. If you follow all these, you would show up “fresh” on race day! This is smart training.

Consistency is Key

I’m sure you’ve heard this a million times but when you’re consistent, you will feel the difference. Your body would feel stronger and you would notice how much easier it is to run longer distances. The best part: You’d have adapted to becoming efficient at burning fat!

Be a Cat

Cats sleep 12-16 hours a day. Mark gets 10 hours of sleep every night but it might not be practical for those of us who hold professions other than elite level endurance athletes.

Just remember that a rested body speeds up recovery process and allows us to maximise the gains from each training session so we need to plan for adequate rest as well!

Pump Iron

Strength training plays a key role in improving endurance performance even though this may seem counterintuitive. You can continue to swim, cycle and bike but your performance may hit a wall (no pun intended) or even feel a decline.

Muscle mass is important in endurance performance events as well.


More specifically, functional strength training should be incorporated in your preparation towards completing a triathlon. Mark uses unilateral (i.e. one side of the body) strength training whereby he focuses on one-legged squats for balance and centres most of his strength exercises on compound (multi joint) rather than isolation (i.e. single joint) movements. Engaging multiple muscle groups in a single exercise is central to his strength training programme.

All of this has been incorporated into the strength training program that is in my 90 Day Transformation for triathletes, an intensive 3 month program designed to ingrain the fitness and nutrition habits triathletes need to reach an elite level of performance, which you can learn more about here.

He also acknowledges the increased risk of accidents with age and stresses the importance of functional strength training in older individuals to improve and maintain balance and coordination.

Stop Overthinking or Lose the Champion’s Race Mind Set

Stick to core workouts and incorporate variety when boredom kicks in or when your body needs to be challenged but do not overcomplicate things! Stop over analysing.


You are better off channelling those mental resources towards something more productive like performing at your best. Freeing your mind of noise and clutter enables you to tune in to the way your body is moving and get into the flow (i.e be fully present and engaged in the moment).

Mindfulness and training in nature and allowing yourself to be immersed in the natural environment can greatly improve the quality of your training. If you start connecting spiritually with nature in every training session, it would be easier for you to access this therapeutic space on race day. Inspire. Appreciate. Connect. Trust. Peace.

Food as fuel


Keep things simple. Do not be afraid of fat but do not over eat. Go for high nutrient density foods. Pay attention to micronutrients! Focusing on the quality of your food ensures your body gets what it requires with fewer calories and your digestive system does not need to over work to break all the food down.

Mark advises to do a bit of research on fast absorbing foods/ gels etc. to accurately gauge how much your body can and cannot handle to maintain your target IRON MAN pace. The more conditioned you are in terms of cardiovascular fitness, the better your body would be able to sustain pace with less carbohydrates and the less risk of nausea on race day!

Final Thoughts

Fitness and health go hand in hand so learn as much as you can. Fine tune. Be adaptable and embrace change. Keep learning and evolving. Enjoy the process and stay healthy!

If this feels overwhelming, don’t be discouraged. Join me on my 90 Day Transformation, a 3 month program designed to reboot your your metabolism and build the strength and conditioning needed for ultimate performance.

Like Mark Allen, smart triathletes have realized that without proper nutrition and a strength & conditioning program you will never realize your full potential.
