If you really want to focus on triathlons, you should understand the following two things:
1. Performance in a triathlon is a result of all three events, their transitions, and (for longer races) nutrition. A triathlon is basically a complex time trial. If you go too hard in the beginning or in one phase of the race (i.e., swim and/or bike too fast), your run will not be as good as it could have been and the overall time will be slower. This concept is difficult to grasp, because results of a triathlon include the splits for each sport and athletes tend to focus on the individual splits separately. In general the most efficient way to race a triathlon is to perform the entire race (swim, bike, run, and transitions) at a consistent intensity level. This will result in the fastest possible overall time, even when it means the split in your primary sport may be slower.
2. In order to perform to your fullest potential as a triathlete, you must work to balance your training in all three sports. Balancing the sports does not mean training an equal amount in each sport. It means you need to level out your relative abilities in each of the sports by training in a way to minimize any impact your weaker sports may have on your performance. Quite often this means training only to maintain your strength in your primary sport so that you can devote more focused time on improving your weak link(s). Athletes who come from a strong background in one of the three sports and/or continue to compete in the individual sport events are typically the ones who have the hardest time doing this.
Once you understand these two points and are willing to train and race by them, you will be on your way to reaching your true potential in the sport of triathlon.
