2014: Injury and Commonwealth Games

An injury to Bolt's hamstring in March 2014 caused him to miss nine weeks of training. Having recovered from surgery, Bolt competed in the 4 × 100 metres relay of the 2014 Commonwealth Games in Glasgow. Not in peak form Bolt said that he was attending the Games for the fans and to show his progress since the injury. Bolt and his teammates won the 4 × 100 metres relay in 37.58 seconds – a Commonwealth Games record. This was the foremost competition of the year for Bolt, given no Olympics or World Championships in 2014.

In August 2014, Bolt set the indoor 100 m world record in Warsaw with a time of 9.98 seconds. This was his sole individual outing of the 2014 season. Soon afterwards he ended his season early in order to be fit for the 2015 season. In Bolt's absence, Justin Gatlin had dominated the sprints, holding the year's fastest times, including seven of the top ten 100 m runs that season.
