Worked on core exercises and also leg strength. Planning on long (for me) run on Sat. with a trail run thru the Balboa Park Trails with a group run with the people from http://www.runwithgreg.com/ . Supposed to be about 6 miles but don't make no diff to me cuz my trusty Garmin Forerunner 305 (should post the serial number, too!) will tell me exactly how far, how fast(?), how high, how low, how slow, how now and how now brown cow I done did!!!
