Hey FF I just had the honor of running and mountain biking with the second fastest runner in the state of Nebraska.
He is my neighbors nephew, only a couple years older than me. We hit it off pretty good and ended going mountain biking and running. I could hardly keep up with him, and had to cut it short while he resumed his training. But it felt great training with someone!
The dude is a machine. He runs 80+ miles a week. 4:06 mile.
WOW!!!! That's a bit too fast mate 5km = 3.1 miles
