Join us in celebrating our 15th year when we host runners in our Half Marathon, 10k and 5k as Half and 10k participants run through Sea Lion Cove, African Adventure and New Kingdom of Asia at Fresno Chaffee Zoo, with a grand finish at Chukchansi Stadium. Or choose our 5k run or walk, it doesn't go through the Zoo, but has all of the other benefits of the Half Marathon.

The Half Marathon is a 20 point race in the CLASSIC Runner of the Year Series!
