The Ironman Marathon Execution

Many athletes I speak with like to tell me the pace they want to hit running off the bike in an Ironman. They say things like, "I will/want to start off at 7:00 min/mile and hold on. If I feel good after halfway, I will push the second half pace." Or they will say, "I am going to push hard from the opening mile, trying to stay with my competitors or pull away from them."

There are a few problems with this approach....

- This type of thinking is entirely RESULTS based, not PROCESS based. Athletes focused on a specific pace when they start the run, put their confidence in jeopardy if they don't hit that pace. They will judge their race in that moment. Just because your legs don't give you a pace you HOPE for right away, doesn't mean you can't get it, or that you still can't run well.

- If you've ever done an Ironman, you know there are peaks and valleys of performance and how you feel. Athletes must focus on being smooth and running easy early, seeing what the body gives them, not forcing it.

- Remember, conditions can affect pacing as much as anything. Cool climates, and you can run faster. Hot climates, and you will likely run slower. 

- Pacing on the bike must be executed correctly in order to have a good run. So much of your run success begins before you ever take the first step on the run course.

- Nutrition on the bike must be executed correctly in order to have a good run. So much of your run success begins before you ever take the first step on the run course. (Yes, that is the same sentence). But there is no nutritional plan that will make up for poor bike pacing for your run success.

- When athletes start their long runs in training, they rarely focus or care about what the first mile or two of the run will be paced at. They are just getting started and realize there is a lot of running to do. The same approach should happen for athletes when coming off the bike.

- Many faster athletes might think this makes sense for mid to back-of-the-packers, but not for elites or top age groupers. But actually, what tends to happen is those faster athletes are already running fairly quickly off the bike, even running relatively easy. Think about it, athletes who have a threshold pace of sub 6 mins, are easily running 7 min pace off the bike, with hardly any effort. Point? Don't rush the pace the first few miles, it will happen on its own.

- Recent studying I have done of paces for the first mile off the bike for pro men and women in Kona shows that if you run the first mile faster than 20 secs faster than the average pace you hope to REALISTICALLY run, you are likely going to pay the price. This is for the faster people, where it is especially difficult to run faster, but extrapolate it out and that means about 5% for the age grouper. Point? Don't be faster for the first mile than 5% of the average pace you realistically hope to run for the marathon, or you're committing a race suicide.

- When athletes run a marathon fresh, they can handle a little aggressive pacing early, but will still pay the price eventually if they do it too much. Now think about the difference when an athlete starts a marathon in an Ironman? They have very little reserve or leeway for early aggressive pacing, given the deficit they begin the marathon with. Add in hot and humid conditions, (like a majority of Ironman marathons are raced in), and you begin to see the need to be the best pacer in the race, to maximize potential. 

Stop focusing on the pace, and more on executing good pacing!
