The PB Predictor (Personal Best Predictor) is PEAK’s performance forecasting tool. While PEAKScore reflects your day-to-day readiness and PRiSM highlights injury risk, the PB Predictor looks at the bigger picture - identifying when you’re most likely to perform at or near your best.
It works by analysing your past competition or match data, specifically the sessions leading up to days when you rated your own performance highly (for example, 8–10 out of 10).
The model examines what your:
7-day and 28-day Training Load
Wellness scores
PEAKScores
Heart–Lung Recovery (HLR) index
looked like in the lead-up to those peak performances. It also identifies which types of sessions (such as speed, strength, endurance, or recovery) most commonly featured before your best results.
Over time, the PB Predictor builds a personalised performance fingerprint. If your data today looks similar to the patterns that preceded previous personal bests, the Predictor will highlight that you’re entering a PB-ready state.
The more consistently you log, and the more accurately you rate your own performances, the sharper and more personalised these predictions become.
In short, the PB Predictor connects the dots between what you’ve done, how your body has responded, and when you’ve historically hit top form, giving you a clear signal of when to aim big.
