Yohan Blake, training partner and fellow countryman of Usain Bolt, has a ton to gain at the London Olympics. Blake has worked alongside Bolt so well that an upset seems possible come this summer. Blake took the gold medal in the 100m sprint at the 2011 World Championships, although it is certainly worth noting that Bolt had been disqualified during the event—Blake has yet to defeat Bolt out of the blocks and across the finish line in a major race. Bolt also has better personal best times for the 100 and 200m, the two races they are training for (along with the 4x100m relay that they’ll run together in). Blake might have youth on his side though, setting personal best times last September, while Bolt hasn’t exceeded his superhuman performance in Germany back in 2009. Bolt will have all the name recognition, but be ready for Blake to make a strong attempt at breaking up the party.
