bootcamp on, legs burning

So...2nd night of bootcamp went fairly well. Seemed easier at first, but was burning at the end. I tried #4 of C25K, but failed miserably...my legs were just killing me. I ended up walking several miles, instead. I'll try again tonight. Food went well yesterday, salads twice and healthy tacos to end the evening. This morning, I'm trying my hand at some Greek yogurt...hopefully it's good!
