Many world records are being broken in this year's Olympics, including Norwegian Karsten Warholm's 400 metre record, to Elaine Thompson-Herah's victory in the women's 100m.

Some believe this could be down to the composition of the track, which has been designed especially for the Tokyo Olympics. Andrea Mallauri, from Mondo, the Italian firm that designed this, explains how the new track is made up of two layers - 'the bottom layer provides shock absorption for the athletes, the top part provides the push'. He argues that this provides a fair advantage to athletes as all are able to take advantage of it.
