long shirtless run on tow-path. Basically added 2 miles to 8 mile run. Only 3 guys shirtless: 1 runner w/girlfriend, 1 walker, and 1 biker. very few people - mostly people on bikes. Goal was to finish under 90 minutes. rough going at end; legs and knees very tired. covered in dirt, sweat, and bugs - but great run.
