Distance (m)

Distance (m)

Supply a lap count to get the distance for each lane.

Each lane out from lane 1 adds 2 times the lane width multiplied by π. With the standard widh for lanes (122cm) that means that you should add 2 * 1.22 * π = 7.67 meters (8.38 yards) for each lane.

A standard 400 meter track has lane lengths of

- Lane 1: 400.00m
- Lane 2: 407.67m
- Lane 3: 415.33m
- Lane 4: 423.00m
- Lane 5: 430.66m
- Lane 6: 438.33m
- Lane 7: 445.99m
- Lane 8: 453.66m
- Lane 9: 461.32m
- Lane 10: 468.99m
