Speedrun pace calculator

A run is on pace when the elapsed time is below the sum of the target splits so far.

  1. Target time = 3600
  2. Total segments = 12
  3. Segments completed = 5
  4. Elapsed time = 1420
  5. Sum of best segments = 3380
  6. expected_pace = 12 > 0 ? 3600 * 5 / 12 : 0 = 1500
  7. Ahead of pace by = 1500 - 1420 = 80
  8. remaining_segments = max(12 - 5, 0) = 7
  9. Time left for the target = 3600 - 1420 = 2180
  10. Time per remaining segment = 7 > 0 ? 2180 / 7 : 0 = 311.429
  11. Projected finish at this pace = 5 > 0 ? 1420 * 12 / 5 : 0 = 3408
  12. On pace for the target = 80 >= 0 ? 1 : 0 = 1
  13. Theoretical best = 3380 = 3380
  14. Time saved by a perfect run = 3600 - 3380 = 220

Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

    The formula

    • expected pace = target x segments completed / total segments

    Even pacing is a crude model. Real splits are uneven, which is why runners track per-segment gold times.
