If its nice out I try (and try is the key word) to run/walk/jog somewhere outside instead of the gym. The Worthington Farm at Monoacy Battlefield is one of those places.
The work-out: Run 0.8 miles see this.
Run 0.6 miles and meet these.
Take pictures. Run back, or walk by then. Repeat 3 days a week. Or when weather is nice. Or when I need to remember what a cow looks like.
