My grandfather's birthday, he was born in the 1880s.
Did 7 on the treadmill with 1 mile warm up, 6X 5 minute tempo reps getting progressively faster (7:05 to 6:30 pace) with 1 minute recovery 1 mile cool down.
Planning to xc ski this afternoon (hill reps at Frisco Nordic Center) but that depends on work deadlines.
