Well, I have had fitness obstacles from having broken bones in both hands that meant a cast on one and splint on the other for a couple of months. But I have never had my fitness held up by an injury from the dog.
Rocky broke a toe on his right rear foot. That means that I don’t give him his mile bike ride in the morning. So instead I have been taking a jog (often more of a walk) or a bike ride of my own during or around that time.
I am getting time in, but tempo and distance aren’t as great as previously. I need to plan a specific regimen if I want to get back into racing again. But the key is to keep something going, instead of a stoppage to nothing.
