RunBests

Run Bests shows your personal best running times drawn from your health data.

Outside of a race, runners rarely hit the exact same distance twice. Your "5-mile run" might be 5.1 miles today and 5.05 miles tomorrow. Because of that variation, Run Bests brackets runs within a certain range together.

Just set a target distance (in miles or kilometers) and choose a "margin of error." For example, if you want to find your fastest 5-mile run, set a 0.25 margin and Run Bests will instantly scan your selected date range and pull every run between 5.0 and 5.25 miles into one clean, sortable list.

KEY FEATURES

• Distance Bracketing Group your past runs using a custom margin of error (0, 0.25, 0.5, or 1) so no near-miss gets left out. Margin is applied upward only — a 4.99-mile workout won't count toward 5-mile until it crosses the line.

• Race Time vs. Workout Time For each qualifying workout, see both the time you crossed the exact target distance (race time, GPS-derived) and the full elapsed workout time.

• Best Segment Paces Find your fastest contiguous 1 km, 1 mile (or any distance you pick) found anywhere inside any run — even if your fastest mile happened in the middle of a long marathon.

• Major Races + Overall Records Toggle Half Marathon and Marathon. Plus longest distance, longest duration, and fastest average pace.

*Custom Date Filters Browse PRs across all time, the last 30 / 90 days, the last year, a single year, or any custom date range. Watch yourself improve across a training cycle.

*Tap-to-Sort Leaderboards Inside each category, top 20 by Race time, Race pace, Workout time, or Workout pace.

• Privacy by Design Run Bests reads your running workouts from Apple Health and stores a private local cache on your device. Nothing leaves your phone.
