A product of Racing de Santander's youth academy, Colsa was born in Santander, and he appeared sporadically with the first team (with an unassuming Segunda División 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.
Colsa retired in June 2013 at the age of 34, after featuring rarely for second-tier side CD Mirandés.[7] Starting in March 2015 he went on to work as an assistant coach under former Racing teammate Pedro Munitis, at that club[8] and SD Ponferradina.[9]
