After taking several years off running due to an arthritic injury in my foot, I've recovered enough to start running again and working my way toward a half marathon at the end of this month, I feel like I've been given a new lease of life. However just 10 days before the event I've pulled something in my lower back and am having difficulty even walking and standing. I'm applying heat packs regularly and its easing day by day but my wife reckons the half marathon would be a crazy idea now, no matter how much better it feels. The idea of missing it makes me feel gutted. Anyone had experience of running soon after this type of injury and any words of hope?
