Which could preclude someone from running in a marathon? a slow running pace a serious knce injury

A serious knee injury can certainly preclude someone from running a marathon. Injuries like ligament tears, tendonitis, or severe cartilage damage can not only hinder one's ability to run but can also lead to long-term issues if not properly addressed. Recovery might involve rest, physical therapy, or even surgery in severe cases, making it crucial to listen to your body and consult a healthcare professional before attempting a marathon. On the other hand, a slow running pace might not be as much of a barrier. Many marathons welcome runners of all speeds, and some even have designated “walker” categories. As long as the runner is physically able and healthy enough to participate, training safely and at their own pace can help them cross that finish line, slow or fast!
