Alexis Sánchez specialized in the event that is included in the athletics program at what premier event?
110 metres hurdles The 110 metres hurdles, or 110-meter hurdles, is a hurdling track and field event for men. It is included in the athletics programme at the Summer Olympic Games. The female counterpart is the 100 metres hurdles. As part of a racing event, ten hurdles of 1.067 metres (3.5 ft or 42 inches) in height are evenly spaced along a straight course of 110 metres. They are positioned so that they will fall over if bumped into by the runner. Fallen hurdles do not carry a fixed time penalty for the runners, but they have a significant pull-over weight which slows down the run. Like the 100 metres sprint, the 110 metres hurdles begins in the starting blocks.
Ponce Grand Prix de Atletismo The Ponce Grand Prix de Atletismo is a track and field competition held yearly in Ponce, Puerto Rico at the Francisco Montaner Stadium.

It is considered amongst the most important athletic events in the Caribbean based on the competitive and organizational quality of the event. It was attended by some one hundred athletes and over 10,000 fans, and corresponds to the IAAF World Challenge until 2015. Nearly 20 Olympic and other world medalists competed in the Ponce Grand Prix de Atletismo, "Puerto Rico’s premiere athletic competition".
