Course intel
Two loops, 90 km, along Brasília's wide avenues past the capital's main landmarks. Officially described as mostly flat, but the course sits on a plateau at 1,100 m elevation and the accumulated undulation is close to 1,300 m: not short steep climbs, but long gentle grades back and forth. Mid-April is dry season with strong sun.

Speed score
Rolling terrain is where you overspend without noticing: 20 extra watts on every little rise adds up and empties your legs for the back half. Let power touch the top of the range on the small stuff and leave it there.
