Same pace, lower heart rate. Easy days that stayed easy. RunNerd™ reads across every run you've logged and surfaces what the data says together. Each insight carries its own trend line, so you can see the change it's pointing at.

Easy. Tempo. Long. Interval. Race. RunNerd classifies every run from what your pace, heart rate, and effort show.
Useful when "easy day" runs creep into tempo territory. The classifier doesn't lie to you.
Most runners spend more time in moderate zones than they think. RunNerd tracks where every minute of every run actually lived — Z1 through Z5 — and shows the pattern across weeks.
The 80/20 split shows up here. So does the answer to "why am I tired all the time?"
The Records tab keeps your fastest mile, 5K, and 10K next to your distance, volume, and heart-rate records, with anything set this month at the top.
Tap a record to see the run that set it, the mark it beat, and every time you've broken it.
RunNerd reads from Apple Health, so cadence, elevation, and split data come through at HealthKit's resolution. Garmin runs come in at full resolution — lap structure, cadence, per-second heart rate — through the direct Garmin connection.
