Ran 10 miles around Sherman Army Airfield while my Dad biked beside me. I was thinking for that many miles I wouldn't be able to talk much but we chatted the entire time!
It took a little over 2 hours. The weather was great but hot so we kept drinking and sweating!
As for longer, weekend runs: I'll run less than 10 next weekend, then a 13 miler the next and then taper for the Dogwood Canyon 25k!
