The eyes of the world will be focused on the Olympic Games in Tokyo as one of the most dramatic events in the calendar looks for a new champion.

Following the retirement of Jamaican speedster Usain Bolt following the successful defence of his crown in Rio four years ago, a new legacy will be engrained into the history books.

The 100m race is, arguably, the showpiece event of the entire Games and is never short of drama, and is most certainly worth marking in your sporting calendar in what could be the most exciting 10 seconds of the year.

While British hopes for the men look slim before the Games started, rising star Dina Asher-Smith is looking strong, despite withdrawing from the British Grand Prix in Gateshead due to a tight hamstring. However, she will face tough competition in the form of Jamaica's Shelly-Ann Fraser-Pryce, who is looking to secure her third Olympic gold since Beijing in 2008.

That being said, funnier things have happened in sport and we could be in for a shock on the cards in this event.
