The Long Run App

A running & training log built by a runner. Structured workouts, live Garmin pairing, optional AI coaching, Strava sync — your data stays on your device.

The Long Run App is a personal running and training log built by a runner, for runners. Everything stays on your own device — no account required, no ads, no tracking.

TRAIN WITH A REAL TRAINING LOG • Import runs automatically from Apple Health, or bring in .fit/.gpx/.tcx files directly • See your current Fitness (CTL), Fatigue (ATL), and Form (TSB) at a glance, based on established training-load science • Get an honest read on training phase, fatigue, and ramp-up risk in the Coach tab

PLAN AND BUILD WORKOUTS • Lay out a full training plan with a weekly-pattern generator, or import one from Excel • Build structured interval workouts — warm ups, hard efforts, recoveries, repeats — with pace, heart-rate, or effort targets • A Workout Library keeps every workout you've built, whether or not it's attached to a day

CONNECT YOUR GARMIN WATCH • Pair a Garmin watch directly over Bluetooth for live GPS/heart-rate/cadence streaming during a run • Push structured workouts straight to your watch from the Mac companion app, by cable or via Garmin Connect

DIG INTO EVERY RUN • Deep Dive into any run's zones, route, and pace/HR/elevation charts, synced and scrubbable together • Automatic VO2max/VDOT estimates and predicted race times • Endurance and Hill scores, route matching against your own run history, and race-day countdowns

SYNC ON YOUR TERMS • Optional two-way Strava sync using your own free API key • Optional AI Coach commentary using your own API key for Anthropic, Google Gemini, or Groq (Groq's free tier costs nothing) • Sync between your own iPhone, iPad, and Mac with no cloud account needed

This is a real, actively-used app — I run with it every week and keep improving it based on my own training. Feedback welcome
