I would start with the foot mobility drills prior to all of your walks. I found that really helped circumvent most of the pains I get when running.
"And for crying out loud. Don't go into the pain cave. I can't stress this enough. Your Totem Animal won't be in there to help you. You'll be on your own. The Pain Cave is for cowards.
Pain is your companion, don't go hide from it."
