Swimming Splits vs SplitSwim

The app is intended for swimmers and their coaches. Using the app is pretty straightforward. The user picks the swim event of their choosing and the target time for that event and the app recommends optimal splits for that time. Though the algorithm for recommending splits is simple (using percentage of speed for each part of a race), it is not really possible to calculate the times during a swim meet without a tool like this app. The swimmer and his coach can then discuss the splits before the race. After the race they can compare the recommended splits with the actual splits from the race. There is an optimal split ratio for middle-distance and long-distance swimming events based on the current scientific discoveries. The first quarter of the race should generally be the fastest. The second quarter of the race should be the slowest and the third and the fourth quarter should be slightly faster then the preceding quarter of the race because of the increasing amount of energy supplied by the anaerobic energy system. The difference between quarters of the race also depends on the stroke as butterfly is the most exhausting and strokes change during the medley events.

SplitSwim is the split calculator built around how you actually race. Most split charts assume even pacing. Real swimmers don’t race that way. SplitSwim reads your personal bests, scores you on a sprinter-to-distance index, and builds target splits for the event and goal time you choose — so the 100 free plan for a sprinter is not the same plan as the one for a 500 free specialist.
