World and Olympic 100m champion Shelly-Ann Fraser-Pryce is down to run the 400m at the UWI Invitational on Saturday (21 March).
Fraser-Pryce, who won the 2012 London Olympic Games 100m and the sprint double at the 2013 Moscow World Championships, is looking forward to her one lap race.
"Thinking about my 400m later and the thoughts are not good lol!!," tweeted Jamaica's sprint queen.
Other Olympians such as Hansle Parchment, Edino Steele and Rosemarie Whyte are down to take part.
