The Fastest Runners on Earth

Last night was an easy 5K on the treadmill while watching the HEAT game.

Got in the 5K I missed on Sunday!
Got in the 5K I missed on Sunday!

Every time I see LeBron now I wonder what his 5K time would be. He’s an incredible athlete used to sprinting around, but he is also made up of 250lbs of muscle…  (Meg: I think you could beat him in the 5k AND the 10k!)

After Google’ing around for the 5K times of professional athletes, I came across an interesting Instagram vid of Ochocinco.

You can think what you want about Ocho (aka Chad Johnson), former NFL player, but there is no denying that the man is FAST.

Here he’s doing “10.0 incline at 20mph. 5 seconds on, 20 seconds off, 5 seconds back on. (5 sets).”

Just in case you’re wondering 20mph is 2:59 minutes per mile pace. Obviously Chad’s only doing it for 5 seconds, but I still think that’s pretty impressive! My speedwork feels a little bit embarrassed by his speedwork!

Chad has also recorded himself running at 24mph with a 2.5% incline for 6 seconds:

And while we’re at talking about fast humans, Usain Bolt once reached a top speed of 27.49 miles per hour!

Of course that’s nothing compared to cheetahs — they can accelerate to 60MPH in under 30 seconds and can reach max speeds of 70-75mph!

Cheetah kitten ... looks just like Cecil.

10 Fastest Mammals According to Wikipedia:

Just this once you’ll have to excuse me for using Wikipedia as a source.

  1. Cheetah | Max speed: 70 – 75mph
  2. Free-tailed bat | Max speed: 60mph
  3. American Antelope | Max speed: 55mph (the fastest long-distance runner)
  4. Springbok (African Antelope) | Max speed: 55mph
  5. Wildebeest | Max speed: 50mph
  6. Blackbuck Antelope | Max Speed: 50mph
  7. Lion | Max Speed: 50pmh (females are faster than males!)
  8. Greyhound | Max speed: 46mph
  9. Jackrabbit | Max speed: 45mph
  10. African Wild Dog | Max speed: 44mph

And I just have to add #11: the kangaroo can reach a max hopping speed of 44mph!

Here’s a cute video of a small kangaroo hopping around some other small animals.

He’s just hopping around playfully, but it still looks kind of fast!

If you’re looking for an excellent read about how you can increase your speed, check out THIS POST from Cori @ She’s Going the Distance. She shares how she PR’d in 9 half marathons in a row (she went from a 2:24 to a 1:39).

Did you know the wildebeast could run so fast? I was shocked! 

– I didn’t realize any species of bat could fly so fast either.

    Ooh thanks for the beating Lebron support! Something I didn’t take into consideration… his legs are prob twice as long as mine!!! That kangaroo is soooo cute and he is pretty fast! I could envision him building up a ton of speed!

      Your sub 6 minute mile in 90 degree heat gives me complete confidence in you!

    Love the Kangaroo 🙂 Thanks for the shout out

      Love that post, Cori!

      The ‘roo is too cute, how do they hop so fast?!

    2. Lou @ Running Through China

      Hi Cori. Just wanted to say that I loved your post, thanks! But for some reason this computer I’m using (a Chinese one that blocks some sites) was giving me grief re: posting a comment on your site. SO, I’m telling you indirectly through here, haha… Thanks, was a very helpful post, and I’m really hopeful that I may be able to PR at my next half after all. Cheers!

    Ok first off, I was expecting way more coverage of the Heat. We are up 3-1 going home to close out the series, plus you have tickets…. come on lol

    That speed work by Chad is nuts. Makes me think I need to man up and step up my speed work. Great info on the animals, crazy how fast some of them are. I read Chris post it was great, it taught me that we can never stop learning in this sport.

      Haha well if I am being completely honest I wrote this post before the Heat game ended so I didn’t yet know if they would win or not … although I was like 99.9% sure they would!

      Chad is ridiculous. Watching his legs go that fast makes me so nervous for him!

    I can’t even imagine attempting to go that fast on the treadmill – I would be totally freaked out that I would go sailing off the back end!!
    Fun to see the animals listed – crazy about the kangaroo!

      I know! When Chad let’s go of the handles on the treadmill I actually held my breath! His legs are moving so fast!

  5. Kristen @ Glitter and Dust

    Chad is crazy! I actually went to college with him and took a class with him at Oregon State (where he played football). I had no idea he was capable of reaching those kind of speeds. That video is awesome! With legs and a body like that, it’s not surprising. Cheetahs are amazing to watch in the wild. When we were in Africa a few months ago, we were able to watch a cheetah stalk and kill an antelope. They run effortlessly.

      Your experience in Africa must have been amazing. The Big 5 Marathon in S. Africa is on my bucket list — the starting time for the marathon depends on where the big 5 game are in the morning!

      Chad is ridiculous – he posted his whole workout using Instagram vids yesterday. The man is a machine! So cool that you got to take a class with him. He seems like a funny guy!

    Why is that cheetah so cute?!

    This was really interesting!!

    Wow, who knew bats were so speedy? Haha… Thanks Kristina, great post! Glad you got your 5km in, and thanks for the link to Cori’s post and blog – was very interesting reading! 🙂

    I can’t believe how fast Chad can run! Most folks speed work in comparison will seem lame now lol I wish I could charge as effortless as the animals you listed. My guess is Cecil thinks he’s a Cheetah 🙂 Cats are funny mine will charge up and down the stairs like crazy for a few minutes then go crash for 6 hours.

      Hahah yes exactly! Cecil runs like a mad man and gets himself out of breath. Then he lays down and huffs and puffs until he falls asleep 🙂
