About
Performance is a finish-time forecasting engine for endurance and hybrid athletes. We built it because every other app showed us heart rate, TSS, and form scores - and none of them answered the question we actually cared about: am I on track for race day?
Performance takes your training history and a baseline fitness number, and produces a probabilistic finish-time projection for your race. That forecast updates every time you log a session. You set a target and a stretch goal, and you can see the gap close - or open - in real time.
We cover Marathon, Half Marathon, 10K, 5K, and Hyrox. All five formats get the same treatment from the forecasting engine. No race type gets preferential treatment.
The forecast is built on physiological principles pioneered by Banister and extended through subsequent research. For running formats, the impulse-response model is well-validated. For hybrid sports like Hyrox - where strength, aerobic capacity, and transition efficiency interact differently - we incorporate format-specific empirical data as it becomes available, so the model stays current with how these sports are actually being raced. We do not generate a single number because a single number is a lie. You will always see a confidence band.
Performance Coach adds a prescriptive analytics layer on top of the forecast. Given your current load, race runway, and the gap between your forecast and goal, it derives the race-specific week-by-week load distribution to close that gap. The plan recalculates as your training history and forecast change - not guessing, but re-deriving the answer each time from the numbers. The difference between knowing where you will finish and knowing exactly what to do about it.
Performance is built by LGT, a small team of athletes and technologists. We run, we do Hyrox, we care deeply about getting the math right. The product lives at performance.lgtnow.com.
