Cycling & running events in Foz do Iguaçu, 2026

Foz Training Notes

Running: Foz runners keep it simple and use the known loops. The Barragem da Itaipu Hydroelectric Power Plant route gives you 3.5 km when you want a short steady run. The CTG Charrua route runs around 5 km, and Avenida Araucária adds a 1 km extension when the legs want a little extra. The Paraná Avenue route goes around the 34th Battalion and covers 4.5 km. Cataract Iguaçu gives you 14 km with trails when you want dirt underfoot. GRESFI Club is the local name to know. The Cataratas Half Marathon and 2ª MEIA MARATONA DE FOZ DO IGUAÇU - 2026 are the anchor races.

Cycling: Foz riders treat the city like a base-miles town. Locals roll east on BR-277 toward Paranaguá or point west toward the Friendship Bridge to Ciudad del Este when they want road time. The city sits at 173 m above sea level, so the climbs are not the main headline here. The work comes from steady Z2, heat, wind, and repeatable intervals. GRESFI Club is the club name that comes up for training life. The Cataratas Half Marathon gives the city its big endurance feel, even if the brief gives no named crit, gran fondo, cyclocross, singletrack, or cycling race.

Season: Foz works year-round if you respect the season. Summer brings an average temperature of 26.5°C, and the heat can reach 40°C, so locals start early and keep water close. Rain is common in summer, and frequent thunderstorms can move a run or ride fast. Winter changes the feel more than the map. Winter averages 15.4°C, and the cold can drop to -5°C, so runners and cyclists get drier air, sharper mornings, and better windows for tempo, intervals, or longer Z2. The same routes stay useful, but the pace feels different.
