Isidro del Prado was initially a Philippine 400 and 800 metre runner, but he focused more on the 400 later in his career. At the 1979 ASEAN School Games he won both events. In 1981 he won the SEA Games 400 in 47.10, a Philippine record, and in 1982 added a victory at the ASEAN Cup in Kuala Lumpur. That year he also made the final of the 800 at the Asian Games. In 1983 he again won the SEA Games 400, running 46.40, also placing second that year at the Australian Championships, and running at the inaugural World Athletics Championships. In 1985 he anchored the Philippine 4×400 relay team to a victory at the SEA Games in Bangkok. During his career he improved the Philippine 400 record seven times, leaving it at 45.57, which he ran in 1984 at the ASEAN Cup. Del Prado later became a coach, guiding the Philippine team for many years, and in 2009 taking over the Brunei national team.
Personal Best: 400 – 45.57 (1984).
