Come on guys. I suck at math.
60 Minutes multiplied by Distance divided by Time equals speed. The formula.
60*D / T = S
60*1(mile) / 7.5(your time) = 8 mph.
Running 1 mile in 7:30 is 8mph.
----------------------
For 1 mile in 10 minutes...
60*1(mile) / 10(time) = 6 mph.
And for the record... I really do suck at math.

I hopped in the car and used the odometer to figure out my "home-locale" running route. I took off a tenth of a mile since I run in a giant circle so to speak and on the sidewalk (inside of the road).
Track markers are much easier though and won't burn the gas.

On a typical high school track, one lap is approximately a quarter mile.
You can also use a football field.
Bring a stop watch. Even the 5 dollar digital watches you find in regular retail stores usually have a built in stop watch. (Yes, I own one)
