i got home from my ride around town and my wife was waiting, ready to run. we walked a few blocks and then started running. she did much better in the cooler air. the breeze kept the heat under control. later today it's supposed to get up to 104F! ugh! glad the AC's working in our house. my wife did a great job, running the entire first mile without stopping. we walked for a bit and then ran another mile without stopping. after another short walk, we ran on in to the finish of 5K. we hit that near our house and walked around the block.
