I ran the 40 for the first time this last weekend, and did it in 5.7 seconds. I know that's no too fast, but for 35 y/o, 5'11" and 265 lbs, I was happy with it. I ran it in 5.1 seconds in high school at 190 lbs. I'm pretty motivated now to see if I can improve this time. I can run distance, but sprinting has never been my cup of tea.
