July is shaping up as a busy month for Usain Bolt, who on Monday committed to running a meet in Lausanne.
The six-time Olympic champion and world-record holder at 100 and 200 meters missed much of last season with injury.
After recently announcing that he will run the 100 in Paris on July 4, Bolt has added the 200 at the Athletissima Diamond League meet in Switzerland the following week.
The sprinter holds the 200 record at 19.19 seconds and has set a goal for himself to become the first man to break 19 seconds at that distance.
He said that he chose to compete at Pontaise Olympic Stadium "because it has one of the best curves in the world."
The world championships will be held in Beijing in early August.
