Nassau, Bahamas: Six-time Olympic gold medallist Usain Bolt will face a showdown against American arch-rival Justin Gatlin at this weekend’s IAAF World Relays in the Bahamas.

Bolt, who has anchored Jamaica to two Olympic titles and three world golds in the 4x100-metre relay, missed last year’s inaugural competition in Nassau in an injury-ravaged season. Gatlin was also an absentee.

In last year’s 4x200-metre relay, Jamaica set a world record of 1:18.63 at the inaugural relays, one of three world records to fall in a truly memorable first edition of the latest addition to the roster of IAAF competition.

And with the bigger goal of the World Athletics Championships in Beijing in August, both sprinters have decided that they will be on show this time around, possibly in both the 4x100 and 4x200m relays.

“It’s going to be serious business for me in The Bahamas,” Bolt said.

“The harder I run the better I’ll get over the races so I have to run hard to get my body used to competing and running hard and just to get into race sharpness.

“I need to get into race sharpness so when I go on the circuit I’m at the best and that’s the main focus.”

Bolt recently ran a 20.20 seconds 200 metres at a meet in his home town of Kingston, Jamaica.

He will face a 33-year-old Gatlin who last season topped the rankings in both the 100 and 200 metres, the 2004 Olympic gold medallist who served a four-year doping ban having posted the fastest times in each event, 9.77 and 19.68sec respectively.
