Alright, so today I’m gonna spill the beans on my little deep dive into Justin Jefferson’s 40-yard dash time. It all started with me just being curious, you know? Like, we all know he’s fast, but how fast exactly?

First thing I did was hit up Google, of course. I started digging around for his official combine results. It’s kinda wild how much info is out there, but you gotta sift through a lot of junk too. I ended up finding his official time from the 2020 NFL Combine: 4.43 seconds. Not bad, not bad at all!
But that wasn’t enough for me. I wanted to see if I could get a feel for that speed myself. So, I decided to try and replicate a 40-yard dash. I know, I know, I’m no NFL wide receiver, but I figured it’d be fun.
I headed down to a local track. Let me tell you, just measuring out 40 yards is a little longer than you think! I grabbed a measuring tape and marked it out as precisely as I could. Then, I got into a starting position, watched a few videos of guys doing the real thing to get the stance right(ish), and just went for it.
I used my phone’s stopwatch to time myself. The first attempt? Embarrassing. Like, seriously slow. I think I clocked in around 6 seconds. I’m blaming it on the shoes. I was wearing some old running shoes that had seen better days, haha!
I tried a few more times, focusing on my start and trying to stay low. I managed to shave off some time. My best run was around 5.5 seconds. Still a far cry from Jefferson’s 4.43, but hey, I’m an amateur!

Here’s what I learned:
- Running a fast 40 is HARD. It’s not just about raw speed, it’s about technique, explosion off the line, and maintaining form.
- Jefferson’s 4.43 is seriously impressive. Understanding what that actually feels like, even at a slower pace, gives you a real appreciation for his athleticism.
- I need new running shoes.
It was a fun little experiment. I definitely have a newfound respect for NFL players and their speed. Maybe I’ll try it again sometime and see if I can improve. But for now, I’m sticking to watching Justin Jefferson do his thing on Sundays.
Key Takeaways:
- Justin Jefferson’s 40-yard dash time is 4.43 seconds.
- Trying to replicate it myself gave me a better understanding of how fast that really is.
- I’m not nearly as fast as an NFL wide receiver. Shocker!
