Pérez's career has not been without challenges. In 1993, he suffered a clavicle injury and a hernia just before the 1999 World Championships. He battled pneumonia in February 2003, affecting his performance at the IAAF Challenge. In 2005, he injured the ligament in his right knee just before the World Championships. A year later, he tore fibres in his left femoral muscle, requiring a four-week rehabilitation program.
Outside of athletics, Pérez enjoys reading and writing. His personal life is marked by unique stories such as his religious promise after winning the 1996 Olympic title. He walked 459km from Quito to Cuenca to fulfil this promise. Additionally, he was promised a lifetime supply of yoghurt after his Olympic victory.
Pérez plans to retire after competing in the 2008 Olympic Games in Beijing. He aims to win a medal at these games before concluding his illustrious career. Post-retirement, he intends to focus on JP Sport Marketing, an organisation he founded in 2001 to promote young athletes.
Pérez is proficient in both Spanish and English, which has helped him navigate his international career effectively.
Pérez's name has an interesting backstory. His mother initially wanted to name him 'Jersinio', but it was not accepted by the Azuay Civil Registry as it did not correspond to the Spanish language. His older brother Fausto eventually suggested the name 'Jefferson'.
Jefferson Pérez's journey is marked by significant achievements and personal stories that highlight his dedication and resilience in the sport of race walking.
