February 29 | 10am - 2pm
Keep An Eye Out for The Next Cow Key Channel Bridge Run - Date To Be Announced Soon!

Sleep Late, Cross a Bridge, Get the T-Shirt

The world’s first zero-k started as a joke between friends mocking the grueling 7- Mile Bridge Run. They wanted to cross a bridge and get a t-shirt without waking up early or breaking a sweat, so the Cow Key Channel Bridge Run was born. Measuring about 300-feet long, The Cow Key Channel Bridge is one of the shortest bridges in the Florida Keys. The event has grown into one of the island chains’ most anticipated events, with runners, walkers and watchers from all over the world dressing in cow costumes and competing for Golden Calf Awards. Free rum shots are handed out at the finish line, where the runners form a parade and stroll to a nearby hotel for a bovine infused after-party and award ceremony. Bring your cowbell. This is a true Key West bucket list event.

Our next Zero K is Saturday February 29, 2020!
