A product of Racing de Santander's youth ranks, Colsa was born in Santander, and he appeared sporadically with the first team (with an unassuming second division stint with CD Logroñés in between) during his first four seasons, although he scored three goals in 19 games in 2000–01, with the Cantabrians being relegated from La Liga.
After representing Atlético Madrid, Real Valladolid and RCD Mallorca, Colsa returned to Santander for 2006–07 campaign, as an undisputed starter and one of the team's captains. In his second season in the second spell he appeared in all the matches as Racing achieved a first-ever qualification to the UEFA Cup, and netted two times.
Colsa retired in June 2013 at the age of 34, after appearing rarely for second level side CD Mirandés. Starting in March 2015 he went on to work as an assistant coach under former Racing teammate Pedro Munitis, at that club and SD Ponferradina.
Colsa was part of the Spain squad that won the 1999 FIFA World Youth Championship in Nigeria, contributing with four appearances to the feat. He made his debut for the under-21s on 9 October of that year, in a 2–1 home win against Israel for the 2000 UEFA European Championship qualifiers.
