Days like today are the reason I run. WOW! I started and ended strong. Breathing was controlled and easy. My lungs didn't feel like they were going to explode (unlike my last two runs). I had no major aches or twinges to work out. I feel great! Plus I took another 15 seconds off my mile pace. w00t! I'll be back to my pre-Burn pace in no time....I'm sure of it! Smiling, breathing...happy.
