Many triathletes record an entire race or brick session as a single multisport FIT file, which can be a struggle to analyze. This Multisport FIT Breaker lets you upload one multisport file, sanity-check power and heart rate on a chart, adjust the swim–bike–run transitions, and export the selected leg as a clean TCX or JSON file. You keep all the key data fields (power, cadence, heart rate, GPS, altitude), but with each discipline isolated so tools like WKO, TrainingPeaks, or other analysis software can treat them as normal single-sport workouts. Whether you’re cleaning up a race file, separating bricks for better tracking, or preparing data for aero testing, this tool turns messy multisport files into usable segments in a few clicks.

Note: I am working on exporting .fit but I need more coffee. right now the current version will work just fine with WKO
