Michael Phelps has outkicked pretty much every swimming pro in the world, so now the dude is taking on the animal kingdom. The 23-time Olympic gold medalist is reportedly racing a real-life great white shark to kick off the Discovery Channel’s infamous Shark Week. While that seems pretty exciting, we couldn’t help but think of some other animal vs. athlete challenges we’d rather see go down.

1. James Harrison vs. a Bear
If you follow the veteran Pittsburgh Steelers linebacker on social media, you already know this dude is a beast. Not only is he amazing on the football field, but he’s ripped and fast as hell, too. We’re pretty sure no one would want to meet him in the woods for a match, especially when he’s pissed off. So why not a grizzly?

2. Usain Bolt vs. a Cheetah
From our elementary school years, we’ve all learned that the cheetah is the fastest mammal on earth. So why not have the fastest man God’s created go head-to-head with the quickest animal? We’re thinking Bolt may lose this battle, though. He’s been clocked at 28 MPH, while a cheetah reportedly can run more than 70 miles per hour.

3. Conor McGregor vs. a Gorilla
McGregor thinks he can beat anyone—in an Octagon or a boxing ring—so maybe he needs a new challenge. Gorillas are smart, huge and strong, and don’t you think it would be kind of funny to watch one sling its shit at McGregor? Just sayin’.

4. Simone Biles vs. a Monkey
U.S. Olympic gold medalist Simone Biles is known as the world’s best gymnast. What animal could put her flipping skills to the test? We’re thinking a monkey. When Googled, monkeys come up as the world’s best non-human gymnastics pros. It would be pretty epic to see her take one on. And let’s be honest, a monkey would look hi-larious in a leotard.

5. Eddie Hall vs. an Elephant
Who wouldn’t want to see the 2017 World’s Strongest Man go up against one of the strongest land animals out there? Eddie is the only man to deadlift 500 kilograms under Strongman rules. An elephant can lift approximately 300kg. However, they have been shown to be able to carry about 500kg of logs with their teeth. So really, it would be a pretty damn good contest to watch go down.
