Xavi won the title of Champion of Spain in the long jump with a mark of 5,82 m, while still preparing with his guide, Enric Martin, for the World Championships Doha 2015 and the Paralympic Games of Rio 2016, his two next challenges.

When he was fourteen, he joined ONCE and moved to the Center for Educational Resources Joan Amades in Barcelona, where in athletics he discovered extra motivation to live with his blindness, besides combining sport with his studies of Administrative Management.

Xavi is also part of the ADOP plan, managed by the Spanish Paralympic Committee, being considered an athlete ARC (High Performance Catalan) by the Generalitat de Catalunya.

This change was providential because it enabled him to hang his first Paralympic medal, a bronze, with his eyes on the track at that time, his guide Raul Sabaté.

After an injury which deprived him of competing at his level the following year at the World São Paulo Games, (Brasil 2007) where he participated in the triple jump getting a creditable sixth position, Xavi Porras had to wait until the World Cup in Nueva Zelanda 2011, to become a champion of the long jump with a mark of 5.99m; while he was getting a new bronze medal as a member of the Spanish 4 × 100 relay team with Martín Parejo Maza (T11), MaximilianoÓscar Rodríguez Magi (T12) and Gerard Descarrega Puigdevall (T12) with a mark of 45.45.

In Lyon (Francia 2013), he came back to the podium with a bronze medal in the long jump, with 6,24 m. His international debut came in a European Championship (Lisboa 1999), obtaining, with his first guide, Sergio Segón, a creditable fourth position in the 100 meters, which reaffirmed his commitment to the sport, to the detriment of football, his passion as a child.

Two years later, in Assen 2003, he repeated his performance with two new bronze medals in the long jump (6,06m) and 4x100 respectively, becoming one of the best European sprinters and jumpers and endorsing his status in the championships of Espoo (Finlandia 2005) where, in addition to greatly improving his brand in length, he was proclaimed runner-up with a record of 6,19m and brushes the podium in the final of the 100 meters.

His next continental appointment was Rhodes (Grecia 2009), which added three more medals on a brilliant performance: gold[7] in the triple jump (12,76m), silver in length (5,90m) and bronze in the 100 (11.90").
