The Portugal Half Marathon runs through Lisbon every October, starting on the deck of the Vasco da Gama Bridge and finishing at Praca do Comercio on the Tagus riverfront. The 21.1-kilometer course crosses the longest bridge in Europe, then continues past Parque das Nacoes and along the river into the historic city center. First held in 2000, the race carries World Athletics Elite Label status and regularly draws top Kenyan and Ethiopian runners. Hyundai has been the title sponsor since 2022; the race previously ran under different sponsor names.
