What is a Half Ironman?

For those of you that have participated in the realm of short course triathlon, you might be thinking about upping your training schedule and racing experience beyond the Sprint or Olympic distances to the Half Ironman distance.  What exactly does this entail and how should you train for it?

A Half Ironman is obviously just another distance of multisports racing – it’s not necessarily a Herculean feat just because it has the word “Ironman” contained in the name so don’t let that intimidate you.  In the Sprint Tri, you swim for 1.5km, ride for 20km, and run for 5km – Not too scary of a proposition for a beginner triathlete.  In the Olympic competition, you swim just shy of 1.5km, cycle for 40km and finally you’re on your feet for 6.2 miles.  If all that sounds tiring enough, the Half Ironman means swimming for 1.two miles, cycling for fifty-six miles, and running for thirteen.1 miles (a half marathon).  The next mainstream competition that’s harder than this is the “full” Ironman, which is swimming for 2.4 miles, biking for 112 miles, and running for 26.2 miles. (I say it’s “main stream” since there are other even longer distance triathlons known as “ultra-triathlons”.

Any athlete serious about competing in a multisports race or someone that really wants to test their endurance and skill should think about working their way up to the Half Ironman event.  While competing and finishing a Sprint or Olympic event is a feat in itself, not many triathletes seriously consider the Ironman distance – it is really a big commitment in time and effort!  So, planning to compete in the Half Ironman allows you to push yourself to the limit of endurance without having a goal that’s out of your reach.

If you’re serious about the training for a Half Ironman, one important thing is to pace yourself in terms of your training schedule.  Simply doubling up on your training or pushing yourself beyond your limits or skill is not going to prepare you properly.  Any triathlete worth half his salt can tell you that for any race – regardless of distance – you need to work on your strength and speed as well as your endurance.  Depending on your own strengths and weaknesses you may need to either work on flexibility – as it really helps in endurance sports, or simply slim down so that you can cover the distance without carrying any extra weight.  Weight training specific to the triathlon disciplines is also important, but obviously not pushing huge weight in the gym which is not functionally beneficial for swimming, cycling or running is not efficient use of your training hours – triathletes are not bodybuilders!  Many people training for longer events like the Half Ironman invest in various tools to help their performance and maximize their training schedules, for example: a bike power meter (ie, a Powertap or Computrainer), heart rate monitor, run pace monitor (like a Polar or Garmin) so they can track their individual output over certain distances under different types of training load and guage any fitness gains (or even losses suffering from overtraining or fatigue!).  It’s also beneficial to train with a swim coach or masters swim group to help improve your stroke in the water or a run club to keep you on track and motivated.  A personal coach that specializes in triathlon can also determine if you need to focus on anything specific that will help your performance on race day – which may include mental blocks and not only the physical requirements (general race anxiety, fear of open water swimming, fear of failure, etc etc can be a huge limiter for performance.)

Training for and competing in a Half Ironman Triathlon could possibly be one of the most challenging things you’ll ever do, but when you actually finish you’ll see it’s likely one of the most rewarding.
