In the past two years, I haven't taken a single sick day. I've run two half marathons, completed a triathlon, and dabbled in yoga and Pilates. Until last month, the closest I'd come to being unwell was when I wiped out during a run, and scraped up my hands and knees.
Recently I realized how much I've taken my good health for granted. I was training for the Chicago Marathon, putting in about 45 miles a week, when my body started breaking down. It started with plantar fasciitis (left foot), followed by bursitis (right knee), a pulled (right) hamstring and most recently, illiotibial band syndrome (left knee).
