Born in Olite, Navarre, Marañón arrived in the Real Madrid youth system at the age of 19, making his professional debuts with Ontinyent CF in Segunda División, on loan (a similar move occurred in the following season with Sporting de Gijón). He joined the Merengue's first team permanently in 1970, but never imposed himself at the club during his four-year spell (a maximum of 19 La Liga games in the 1973–74 campaign).
Marañón's sporting fate changed in 1974, as he signed with RCD Español: after two slow seasons he would never score in single digits again, also playing European competition with the Catalans, gaining club captaincy and reaching the national team.
Marañón retired in 1986 at nearly 38, after three seasons with Español neighbours CE Sabadell FC, helping it promote to the second level in his first year. He finished his career as the former's top scorer in the top division, with a total of 111 goals; his record would stand for 24 years until another club legend, Raúl Tamudo, broke it in 2007 during a 2–2 draw at FC Barcelona.
Capping off his best season at Español – 22 goals, good enough for joint-second behind Valencia CF's Mario Kempes, as the club nearly qualified for Europe – Marañón made his debut for Spain, appearing in a friendly with Hungary in Alicante, on 27 March 1977 (1–1).
