Notes
Ran on roof so I could take my shirt off in hot noon day sun. Black tank top, 60/40 poly/cotton blend does not do well in heat/ humidity here. 1 length of the roof is about .13 mile, so 1 down and back is about .25 miles.
Did four laps or 1 mile under 10 mins, break to drink/ pour cold water on myself, then two sets of two laps under 5 min per set for a total of 2 miles. Was really gassed at the end.
