The C.R.A Air Force Running 5K is a short race and walk held within Parque Ecológico do Tietê in São Paulo. The primary event is a 5 km run, complemented by a 2.5 km walk for those seeking a less strenuous option. This event is organized by the Associação Comando de Reservistas de Aeronáutica and welcomes both civilian and military participants.
The awards distinguish between civilian, active military, and reserve military categories, with trophies presented to the top five finishers in each. Special prizes are designated for teams, and all participants who complete the race receive a medal. This structure distinguishes it from a typical city 5K, lending it the atmosphere of a community sports day with an Air Force reserve affiliation, concluding with a post-race gathering in the park.
