Warm start, steady finish

Runners will face a temperature rising from 63°F at the start to a peak of 74°F by the finish, with humidity at 69%. Wind will be light at 6 mph, providing a crosswind in the first 9 miles and a tailwind during mile 10, before returning to crosswinds through mile 14. Adjust pacing conservatively early, especially if humidity feels high, and focus on hydration as temperatures increase.

Race Info

The Hyundai Porto Half Marathon runs along the Douro River in Porto, Portugal, each September. The course starts near the Freixo Bridge on Avenida de Paiva Couceiro, heads west past Cais de Gaia and Afurada, crosses back over the Douro on the Dom Luis I Bridge, and finishes at Jardim do Calem next to Clube Fluvial Portuense. First held in 2007, the race carries a World Athletics/AIMS label and has drawn East African winners in nearly every edition, including course records by Zersenay Tadese (59:30, 2011) and Enatnesh Tirusew (1:07:13, 2023). Hyundai has sponsored the race since 2019; organizer Run Porto also puts on the Porto Marathon and Sao Silvestre do Porto.
