Finals of the women’s 200m, 100m hurdles and long jump are among tonight's highlights...
Dina Asher-Smith is the fastest British woman in history, breaking both 100m and 200m national records, and today she will be looking to make her international mark in the 200m final in Rio.
The 20-year-old has been on phenomenal form, taking the 200m gold at the European Championships this year, but she’s well aware that this is the biggest prize.
Other British athletes worth checking out today include Tiffany Porter, who will be competing in the 100m hurdles, and Shara Proctor in the long jump.
Let’s hope that they all make it to the podium.
