Jamaica’s Kenia Sinclair has been Jamaica’s middle distance standard-bearer for years until injury struck her down in 2012.

Three years on, after struggling mentally and physically, she is back and ready for battle at the Racers Grand Prix.

Sinclair, who will be 36 years old in July, is the national 800m with a time of 1:57.88 minutes established some 10 years ago in 2006.

Sinclair is one of Jamaica’s greatest-ever 800m runners and has broken the barriers of Jamaican female middle-distance running.

She has broken the Jamaican record five times in three years.

The 10-time national 800m champion made her long-awaited return to the track in Los Angeles clocking 2:02.32 minutes.

That time makes her the second-fastest Jamaican this year, behind Natoya Goule, who did 2:01.55, and the 64th quickest in the world.

Sinclair, an outstanding runner at St Jago High, will line up against fellow Jamaicans Semoya Campbell and Samantha James, Americans Christine Rodgers, Molly Ludlow, Charlene Lipsey, and Canadians Melissa Bishop and Fiona Benson at the Racers Grand Prix on Saturday, June 11.

It will be a very good test for Sinclair, who is based in Florida, on her return on local soil as several of these runners have dipped below the two-minute barrier in recent times. Melissa Bishop of Canada, with her 1:59.97 minutes achieved at the Rome Diamond League, is the 11th fastest this year and certainly will be the top-ranked runner at 800m in the field.

American Molly Ludlow, who has a personal best of 1:58.65 minutes, established in 2015, will be hard to beat, while Fiona Benson of the US with a best of 1:59.59 minutes, will ensure that the race is properly contested.

Lipsey, the third American in the field, with a seasonal best of 2:01.88 minutes, should also make her presence felt.

Up-and-coming Jamaicans Campbell and James will have their hands full, but it will be invaluable experience for both because of the lack of quality 800m runners locally.

But all eyes will be on Jamaica’s Sinclair to see whether or not she is in the kind of shape that saw her reaching the 2008 Olympic final and twice in the semi-final of the World Championships.

Sinclair, who broke Inez Turner’s 10-year-old 800m record in 2007, was the fifth Jamaican to dip below the coveted two-minute barrier.

In 2006, she grabbed silver in the 800m at the IAAF World Indoor Championship where she also achieved the national record of 1:59.54 minutes in Russia.

In March of the same year, Sinclair earned silver at the 2006 Commonwealth Games, where she had the rare distinction of beating her idol, the three-time World and Olympic champion Maria Mutola of Mozambique.
