Career
He was the gold medallist at the 2015 Pan American Games and the 2014 Central American and Caribbean Games. From Havana, Pérez first established himself nationally at the 2007 Barrientos Memorial meet in Havana, winning the 10,000 metres. He competed only domestically over the next two years, continuing with two further wins at the Marabana Half Marathon and back-to-back titles in the Cuban Independence Anniversary Half Marathon.
There he was the gold medallist in the marathon with a personal best time of 2:19:13 hours.
He surprised on his second international performance at the 2015 Pan American Games: entering only his third marathon, he defeated the more favoured Raúl Pacheco (a Peruvian Olympian) to maintain his undefeated streak at the distance. His finishing time of 2:17:04 hours was a personal best and also reached his objective of running a qualifying time for the 2015 World Championships in Athletics.
