How fast do you sprint?

[GhostFighter]

Im curious for those who know, how fast do you sprint and for how long are you able to keep this?
I myself do 18km/h (11mph) for 2 minutes.

Idk, I used to be able to put in a 4.4 40. Not anymore though ever since I focused on distance and stride length. My leg muscles lost their explosiveness.

It's weird not being able to run fast but your brain remember how to run fast. Must be how RJJ feels.

Back in the day my mile was low to mid 5's. Now 1/8 of a mile takes me about 8-10 minutes, just like Grease Lightning I tell ya........... Rockin'
