Official event pageWhat this race demands
The Maratona Internacional de Porto Alegre demands sustained pacing and running economy over a flat 42.2 km course along the waterfront.
Sustained Pacing
Because the course features only 14 meters of elevation gain, athletes must maintain a steady, uninterrupted running rhythm for the full marathon distance without the natural relief of hills.
Running Economy
The flat profile eliminates significant climbing and descending, placing a heavy premium on efficient, repetitive biomechanics over 42.2 kilometers.
A marathon lasting over 2.5 hours requires consistent exogenous carbohydrate intake of 60 to 90 grams per hour to sustain glycogen levels.
