Maratona da Cidade do Rio de Janeiro pacing strategy

The course is flat and near sea level, but the race starts before sunrise and the second half gets warmer. Run the first 10 km a little under control and keep energy for the heat on the beachfront.

Pacing by course section
Section	Terrain	Advice
km 0–10	Flat roads through Barra da Tijuca, ending with the Joatinga Tunnel	Start at goal pace or slightly slower, because cool air and fresh legs make fast running feel easy.
km 10–18	São Conrado, flat and open	Do not bank time here; hold your goal pace.
km 18–30	Leblon, Ipanema and Copacabana beachfronts, with the biggest crowds	Stay on pace, drink at every aid station and use shade where you can.
km 30–42.2	Botafogo and Aterro do Flamengo	Expect warmer weather; keep the effort steady and push only in the last 3 km.
