I definitely aggravated/injured some stuff. I'm guessing the piriformis and the IT band. Good news is I have lots of time to fix these and my PF. For now, limping is only a minor inconvenience. I love the MCM! It's extremely well run and organized. The Marines stationed throughout the course were unfailingly encouraging, respectful and helpful. The course is beautiful and interesting. Most unique was the strong vibe of honor, duty and remembrance. I hope to actually run all of it someday. Thanks for the kind and encouraging messages. This is a great and powerful little community! Happy Halloween everyone!
