21K Juquehy is a coastal road race in São Sebastião, located on the São Paulo state shoreline. Participants can select from 5 km, 10 km, or 21 km distances, and a 5 km walk is available for those seeking a less strenuous participation option.
The 10 km and 21 km courses are on asphalt, with the event designed around Juquehy’s beach-town atmosphere instead of a typical city course. Yps Promoções e Eventos manages the race, supported by the São Sebastião city government, and awards are presented in multiple categories. This marks the event's third year, featuring a straightforward structure with short, middle, and half marathon distances, plus a walk, all part of the same program.
