IRONMAN Brasilia
IRONMAN 70.3 Brasília is on 18 April 2027, with a calm lake swim, a flat 90 km bike, and a tree-lined 21.1 km run through the planned capital.
The altitude is the fact worth knowing before you enter. Brasília sits at around 1,100 metres, high enough that a hard effort feels different from the same effort at sea level and high enough to flatter nobody who has flown in the day before. If you are chasing a time, arrive early or accept that your bike power will read low.
The compensation is the climate. On the central plateau in April the mornings are cool and dry, and this is a far more comfortable race than the Brazilian coastal events.
The city was designed around wide, straight roads, which is a poor way to live and an excellent way to run a bike course. Brasília has a major domestic hub with connections through São Paulo.
