Name: Ciara Mageean

Event: 1500m

Age: 29

After finishing 11th in the 1500m semi-final at the Rio Olympics with a time of 4:08.07 - nearly seven seconds outside her season's best - Mageean vowed to come back "stronger, faster and better," and has been good to her word.

A silver medal in the 2018 European Championships, a bronze medal a year later at the European Indoor Championships and a PB of 4:00.15, the Portaferry native will be bidding to break the four-minute mark in what will be a highly competitive field.

In July Mageean became the first Irish woman to run sub-two minutes for the 800m, adding to her mile and 1500m national records, and now the focus is to make her mark in Japan.
