During its first 200 years of British rule, Jamaica became one of the world's leading sugar -exporting, slave-dependent colonies, producing more than 77,000 tons of sugar annually between 1820 and 1824. After the abolition of the international slave trade in 1807,  the British began to import indentured servants to supplement the labour pool, as many freedmen resisted working on the plantations. After slavery was abolished, workers recruited from India began arriving in 1845, Chinese workers in 1854,  as many freedmen resisted working on the plantations. Many South Asian and Chinese descendants continue to reside in Jamaica today.  
Hey Jimson! What about Mike Hurst’s 6x200m workout? I know these paces/recovery above are more intensive tempo (except for the later Hart workouts) than special endurance. But after your interview with Mike, I have been attempting his 6x200m workout at 400m (second 200m) goal pace with 200m jog recovery (no more than 2min). I have run all the workouts above, and I can say that Mike Hurst’s workout is BY FAR the most mentally and physically challenging workout I have ever attempted. My goal pace is /high for the 6×200 by the end of the year (currently I have only completed 5×200 at that pace). So far, however, I have noticed a strong translation onto the track for both my athletes and myself. I would highly recommend! But take Mike’s advice and work up to the 6×200 (2x3x200 with 10min between sets, then 5×200 later in the season, finish with 6×200) because this workout will seriously challenge any athlete.
The 2008 season saw a new high for sub-10 second performances: 14 runners achieved the feat a total of 53 times between them, the highest ever for either figure. Furthermore, ten men had achieved the result for the first time in that year – another record. The men's 100 metres final at the 2008 Summer Olympics saw a world record and six men clear ten seconds (equalling the number from the 1991 World Championships). Only two months into the start of the outdoor track season, 2011 became a record-breaking year as fifteen men ran under ten seconds between April and June.  As of 10 June 2013, 86 sprinters have broken the 10-second barrier with an official, legal time. The men's 100 metres final at the 2012 Summer Olympics saw a new Olympic record and seven men dip below ten seconds, with only one competitor failing to do so. However, one of the first seven, Tyson Gay , was later disqualified from this race. Prior to his disqualification, he had been in fourth place with a time of seconds, the fastest fourth place in history.
