In the interests of keeping my leg from becoming seriously injured, I'm going to forgo tomorrow's walk. If the weather stays nice, I may visit Blythe Park so I have a better idea of where it meets the Sammamish River Trail. But I won't walk.
As a replacement, tonight I'm going swimming, and I'll do my crosstraining on Friday as scheduled. Between the two it should make up for some of the workouts I'm missing.
I feel like this must be a pale shadow of what a real athlete feels like when injured. I feel GREAT. I feel strong and healthy. But I can't do what I want to do because it hurts too much. It's incredibly frustrating.
