About 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.

Name a time. Get the plan.
• Goal-pace plans — pick any distance from 800m to the marathon, tell 0to42K how fast you want to run it, and it builds the whole plan around that: every training pace, every session, week by week, right up to a final goal attempt
• Your reps are measured in metres, not minutes — a 400m rep is 400m whether you hit the pace or not, and you'll hear about it if you drift off target mid-rep
• Honest about your goal — if the time you've picked is a big jump from your recent runs, the app says so and suggests a longer build. It still makes the plan you asked for
• Recovery now looks at heart rate variability, measured against your own baseline rather than someone else's average
• Heart rate zones can come straight from Apple Health, so 0to42K and the Fitness app finally agree
• Start a run on your iPhone and your Apple Watch now starts recording straight away, even if the watch app isn't open — with its clock and intervals in step with the phone
• Run indoors from your watch: a new Indoor switch tracks treadmill runs without GPS
• Rating your effort on the watch is now optional — skip it and nothing is logged to Apple Health
• Race course climbs reach your watch as soon as you add a course, and stay there all race day
• Steadier Apple Watch sync — a run tracked on both watch and phone saves the same time and distance whichever syncs first, a deleted run stays deleted, and a pause from an earlier run can no longer land on your next one
• Reset Training Plan now restarts your plan from week 1 instead of clearing it — your next workout stays on the Today screen and new runs count toward the plan again
• The app icon now fills the whole tile, with no border around it
As always: no subscription, no ads. Every feature included.
