4.5 miles.

Today is (officially) the first day of spring break for my kids, so I took them with me to the park so they could ride their bikes while I ran.  Of course, they got too cold and wanted to go home before I was finished with my run, but I was able to get 3 miles in before coming home and doing the rest on the treadmill.  When I finished with my run, I did 15 minutes on the elliptical and 30 minutes of Pilates.
