## What is 0to42K?

From your couch to the finish line. One run at a time.

0to42K is a complete running coach built around a single idea: every feature should be yours forever, the moment you download the app. No subscription. No premium tier. No upsells. Pay once, get everything — including every future update.

TRAINING PLANS THAT MEET YOU WHERE YOU ARE
Pick the plan that fits today, switch any time:
• Aerobic Base — 12 weeks, build your foundation
• Couch to 5K — 8 weeks, your first 5K
• 5K to 10K — 8 weeks, double your distance
• Half Marathon — 12 weeks, finish 21.1 km
• Marathon — 16 weeks, conquer 42.2 km

The app tracks your progress workout by workout and adapts coaching tips based on how you're actually performing — not a one-size-fits-all schedule.

LIVE RUN TRACKING THAT GETS OUT OF YOUR WAY
• GPS route map with elevation profile
• Real-time pace, distance, and heart rate
• Auto-pause that knows when you stop at lights
• Live Activity on lock screen and Dynamic Island
• Audio coach with km/mile split announcements
• Built-in warm-up and cool-down stretches

INSIGHTS THAT ACTUALLY MEAN SOMETHING
Know if you're getting fitter, not just busier:
• VO2 Max estimate from your runs
• Recovery readiness using acute:chronic workload ratio
• Time in each heart rate zone
• Grade-adjusted pace (GAP) for hilly routes
• Cadence trends, negative split detection
• Personal records across every distance
• Run-to-run comparison

APPLE WATCH — LEAVE THE PHONE AT HOME
The companion watch app tracks runs independently with heart rate and GPS. When you reconnect, everything syncs cleanly. Start a run on either device, get the same Live Activity, the same auto-pause, the same Apple Health sync.

WIDGETS, SHORTCUTS, AND APPLE HEALTH
• Home screen widgets for next workout and weekly progress
• Siri: "Start my run," weekly stats, streak check
• Two-way Apple Health sync — runs, heart rate, sleep, resting HR

RACE DAY PLANNER
Set a target race, get a countdown, target pace, and per-kilometer split plan right on your Today view.

SHOE TRACKER, STREAKS, ACHIEVEMENTS
Log your shoes and know when to retire them. Build streaks, hit weekly goals, watch your heatmap fill up.

PRIVACY-FIRST
Your runs live on your device and in your iCloud. No account, no login, no server collecting your data.

ONE-TIME PURCHASE — FOREVER
Every plan. Every chart. Every Watch feature. Every future update. No subscription. No "Pro" tier. Just running.
