# PX7 Training

> A zone-based running platform built on the Norwegian 80/20 method — more easy miles, fewer junk miles, plans that actually adapt to the week you're having.

PX7 Training is a self-serve running training platform implementing the PX7 Training Method: a polarised (roughly 80/20) intensity distribution with workouts anchored to the athlete's actual physiological thresholds (LT1 and LT2). An assessment derives personal zones from a structured test run; seven training zones drive every session, expressed in pace or power; plans adapt when sessions are skipped, missed, or rescheduled. Three subscription tiers: Starter (€9/month, self-guided), Plus (€29/month, adds coach messaging, plan adjustments, weekly digest), Pro (€99/month, adds training review and race-focused refinement). Currently in private, controlled rollout with a public waitlist. The app lives at https://app.px7.training.
