Fernández Anaya was trailing behind Olympic bronze medallist Abel Mutai during a cross-country race in Burlada, Navarra. Mutai was leading comfortably until he pulled up 10 to 20 meters short of the finish line thinking the race was already over. Instead of passing Mutai, Fernández Anaya slowed down and told Mutai to keep running. Since they didn't speak a common language, the Basque runner gestured frantically at Mutai who went on to win the race.
