TO further valildate the impact your book has made on my running, I have been able to complete 4 marathons in the past 4 months. LaSalle Bank, Chicago Lakefront ultra (50K), Tecumseh Trail Marathon, and a personal marathon, which I ran in temps from 0-4 degrees, it was monitored by my neighbor for time and safety. David, after each run. no part of my body felt painful, nor grueling. My health has been better, the legs are comfortable, and each race has marked improvement in style and time. Now, after just one day of rest, my training stays on track. Thank you for your book’s approach to running and life.
