PBSplits
Your fastest splits, found.
A free way to find your fastest split at every distance across all your runs, 1 km, 1 mile, 5 km, 10 km, half, marathon. Pulled from your existing workout data.
How it works
Most personal-best tools only know your finish times, if you've never raced a 5K, they think you've never done one. PBSplits looks inside each run and finds the fastest continuous window for every distance on the ladder, so the best 5K you ever ran shows up even if it was the middle 5K of a 12 K training jog.
Three tabs, and it opens on the first. Runs is every run in your Health data, pull to refresh, tap any one to open it, even the ones that never hit a standard distance. Trends plots a distance over time, as pace or as finish time, with a year-over-year view to lay this season against the last. Bests is the record book: the ladder from 400 m to 100 K, grouped Short / Road / Ultra.
Inside a record
Tap any effort and you get the whole run, the route on a map with the record-winning segment highlighted, a mile-by-mile splits table, and pace and elevation charts. Tap a split and its window lights up on the map and across the charts, so you can see exactly where you found the time. Season and all-time crowns mark the efforts that took a podium.
