Londrina hosts 2 Half Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Locals build easy runs around Aterro Lago Igapó because the park gives you simple Z2 laps without overthinking it. Avenida Rio Branco works when you want a sharper city session, and Track e Field Experience Running puts 4KM, 8KM, and 11KM options there. Cresol Run keeps Aterro Lago Igapó on the race map with a 5KM. Maratona de Londrina is the anchor event, and one measured 2012 course runs 43.25 km while gaining 447 m. MEIA MARATONA PRIME RUN 2026, Eco Run - Londrina 2026, and ULTRAMARATONA 100K NIGHT RUN LONDRINA 2026 keep the calendar busy.

The Londrina to Assaí route is the obvious ride when locals want more than flat base miles. The route runs 53.7 km and gains 632 m, so it feels right for a long endurance day or a gran fondo tune-up. The surface keeps things honest because the route uses 24.8 km of paved road and 28.9 km of unpaved road. The climbs bite up to 5.7%, and the descents drop to -3.8%. Londrina Esporte Clube, Associação Portuguesa Londrinense, and Inesul/Londrina are the local club names to know. DESAFIO MTB SERTÃO - XCM - MARATHON BIKE 2026 gives the dirt crowd an anchor.

Londrina runs on a humid subtropical rhythm, so locals plan training around feel, not just pace. The 2026 calendar gives the city 55 running and cycling events, after 48 events in 2025, so racers can pick goals all year. The brief does not name the best months, and locals would rather point you to the calendar than pretend every week rides the same. Summer specifics are not listed, so runners keep Aterro Lago Igapó practical for short work and riders save bigger Z2 days for the Londrina to Assaí route. Winter details are not listed, but the same park laps, marathon routes, and mixed-surface miles stay in play.
