Athletics at the 1977 Bolivarian Games

The Athletics competitions in the 1977 Bolivarian Games were held at Estadio Hernando Siles in La Paz, Bolivia, on October 15–29, 1977.

A detailed history of the early Bolivarian Games, 1938 to 1989, was written (in Spanish) by José Gamarra Zorrilla, former President of the Bolivian Olympic Committee, and first President (1976-1982) of ODESUR. Gold medal winners from Ecuador were published by the Comité Olímpico Ecuatoriano.

In 1977, total of 37 events were contested: 23 by men and 14 by women.

Medal summary
All results are marked as "affected by altitude" (A), because the stadium in La Paz is located at 3637 m above sea level.

Starting January 1, 1977, the International Association of Athletics Federations required fully automatic timing to the hundredth of a second for events up to 400 metres. Some results in the middle and long distance events that did not have fully automatic timing are marked (a).
