P10–P90 speed · chart guideCandles and bars show the distance-weighted P10–P90 range with a median (P50) mark; the line shows medians. Colors compare actual endpoint speeds: green close ≥ open, red close < open. Endpoints can lie outside the percentile range. Map colors show elapsed average speed. Elevation uses 5 m spatial smoothing, which can soften short hills and may differ from Garmin or Strava. No external elevation service is used.
