Getting ready for the Memorial Day 5K

We are hosting the club's Memorial Day 5K and breakfast at my house next Monday.  Nothing like having an inflatable arch over your driveway and a hundred or so runners in your yard.  Lots of fun.  I modified the course for this year.  This morning, my wife and I walked the course and measured it with an engineer wheel.  I'm not use to walking; it is more tiring than running.  I worked out at Nautilus this evening and then ran laps at the track.
