Illustrative plan; edit for your facility.
- Time per full lap
- 1:16.3
- Distance plan
- 3 full laps+ 378.888 m
407.037 m per lap · lane 2, flat outdoor geometry
Target: 1600 m in 5:00 · 3:07.5/km
Last partial segment: 1:11
Measure the remainder along the selected path. This does not locate painted starts.

L(n) = L(1) + 2π × [(n−1) × lane width + outer offset − lane 1 offset]; L(1) stays unchanged.
Same-speed arithmetic for a measured path or flat outdoor parallel lanes. Actual running position and lane changes vary. This does not locate painted starts, certify a personal best, or model banked indoor tracks.
Rounding is for display. An exact mile is 1609.344m; the remainder is a distance to measure along the path, not a painted-start instruction.
Plan your distance rep
Check the path inputs for your facility. Starting values are illustrative; geometry assumes flat outdoor parallel lanes.
WA uses 0.30m from the kerb in lane 1, or 0.20m from the inner line when unkerbed; outer lanes use 0.20m from the outer edge of their inner boundary line. Lane 1’s own lap stays unchanged. Enter your facility’s actual dimensions.
