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. SMART SPLIT • See your racing style: sprint, mid, or distance • Get personalized target splits for SCY and LCM • Compare your pacing shape with similar top-level races • Recalculate instantly when the goal time changes EVERYDAY RACE TOOLS • Split Calculator — even splits for any event, from a 50 to a mile • Time Converter — SCY, SCM, and LCM with NCAA-style factors • Time Standards — search qualifying times and motivational cuts • Personal bests and indexes stored on your profile, including as a guest HOW IT WORKS Add the times you already have. SplitSwim turns them into a racing-style index, then uses that profile to pace the race in front of you. Pick the event, enter the goal, and take the splits to warm-up. Built for club, high school, college, and masters swimmers who want a plan that fits their race — not a generic average.
