Tip 1 is something that I really have to work hard on in every race I do, and it is not as easy as it sounds.
Progressively build your racing intensity as you move through the each discipline and the race course.
For Ironman this applies to the swim, the bike and the run, and this strategy will ensure you do not blow yourself up early, and live to regret it later.
We can even take this strategy one step further and say that throughout the course of the entire race, work to start out slowly from the start of the and build momentum as you near the finish line on the run leg.
This strategy will help you not only reach the finish line, but more importantly be able to savor the feeling of achieving your goal of finishing an Ironman.
