Common questions

Why is a Lane 2 circuit longer than 400m?

The bends have a larger radius. Starting from the same finish line and returning to it makes Lane 2 approximately 407.04m, with each outer lane progressively longer.

Do these distances work on every track?

They use the standard 400m track geometry and 1.22m lane width. Older tracks, school tracks, and nonstandard facilities may differ, so check posted markings first.

What if I am running fixed 200m or 400m intervals?

Use the Track Split Calculator. A fixed-distance workout should follow the track markings, not treat a same-line outer-lane circuit as 400m.
