Gran Fondo Buenos Aires

Gran Fondo Buenos Aires, officially Gran Fondo Argentina, takes thousands of riders onto the city's main highways, closed to traffic for the morning. There are two distances: a short route of 46 km and a long route of 129 km, both starting and finishing at Parque Sarmiento. Both courses are practically flat, so the race is all about speed, drafting and sustained power — a very different challenge from mountain sportives. On flat terrain, the race is decided by the wind and group dynamics. Strong riders who can hold a high pace at the front will split the groups, while riders who draft well will save energy for the decisive moments. Mid-October is spring in the Southern Hemisphere: the early-morning start usually brings mild temperatures, but wind on the exposed highways can add tactical complexity. Training depends on the distance. The 46 km is short and fast: work on VO2max efforts and repeated surges so you can follow the accelerations without getting dropped. For the 129 km, build sustained threshold power with 15-30 minute intervals and rides of three hours or more, and practice echelon riding in crosswinds. On both routes, an aerodynamic position you can hold on the drops for long stretches will pay off on race day.
