Laura D'Asaro of Seattle is training to set a Guinness World Record for the fastest time to crawl a mile -- as in, crawling a mile on your hands and knees. At 5-10, 135 pounds, the 17-year-old gymnast has the endurance to crawl very fast. After three weeks of practice, she is within 58 seconds of surpassing the record, now at 23 minutes, 45 seconds. On Friday, she trained on the Burke-Gilman trail.
