When Sanya Richards-Ross lined up in the middle of the pack of her 400 field, the runner in lane 8 was way out in front.
She wasn't getting a head start. The curves in the track mean the outside runners would have to run a longer race if they all started in the same position.
So the starts are staggered along the track with lane 1, the closest to the infield, being the furthest back.
They don't need to do that in the 100 because the runners don't have any curves to negotiate.
