Samson Stomp

Registration Details:

Online registration is open for all races until noon on January 14, 2026. Entry fees include a long-sleeved T-shirt, Zoo admission, beverage, snack, and parking.

After the event, participants are invited to enjoy the remainder of the day at the Zoo.

The race will be held rain or shine, snow or cold; however, the Milwaukee County Zoo reserves the right to cancel due to severe weather or dangerous, unforeseen race conditions. No refunds will be given.

The 5K race is officially timed; results will be publicly available in person and online after the race. All races take place on public walkways throughout the Zoo. Due to safety concerns, no strollers, in-line skates, or similar devices permitted.

During the event, take part in our mission of conservation by donating your old handheld electronics — cell phones, tablets and e-readers, smart watches, earbuds, digital cameras, digital music players, wearable fitness trackers, handheld gaming systems, and GPS devices — at the Zoo for recycling. The drop-off area is located in the Zoo’s U.S. Bank Gathering Place.

Recycling handheld electronics reduces the demand for coltan, a mineral extracted from the forests of Congo, home to critically endangered lowland gorillas. The coltan mining business has led to a dramatic reduction of the gorillas’ natural habitat.
