Some of the world鈥檚 biggest names in swimming and athletics battle for the podium on a remarkable night of Olympic sport as Britain go for gold in the pool and on the track.

All eyes will be on the women鈥檚 100m, one of five athletics finals, with Great Britain鈥檚 Dina Asher-Smith set to take on Jamaica鈥檚 Shelly-Ann Fraser-Pryce and American Sha鈥機arri Richardson.

There are also four gold medals to be decided in the pool, with Team GB seeking to defend their Olympic title in the mixed 4x100m medley relay. There are likely to be fireworks in the men鈥檚 100m butterfly as reigning champion Caeleb Dressel attempts to hold onto his crown, while the women鈥檚 800m freestyle, featuring Katie Ledecky against Ariarne Titmus, promises to be a race for the ages.

Hosted by Clare Balding and Gabby Logan.
