DH and I have started running in the past few weeks (we're training for the Tough Mudder in May). The first few times were fine, but now as soon as I start running my knees hurt and don't let up. It doesn't hurt during my normal activities, just when I start to run. I'm not sure if a brace would help, if it's my shoes, if I "have bad knees", or something else. I'm not looking for a DX online, just curious if anyone else experienced something similar and was able to resolve it easily.
