Yes, I have run in the summer before but not like this. I started running fall of 2010. I ran my first marathon the first weekend of June 2011 and pretty much took the rest of the summer to recover just a few runs here and there. Summer of 2012 was spent just trying to recover from pregnancy and an early May c-section. And last summer I was just totally spent after a spring where I ran several marathons and my first 50K. I ran every week but was probably averaging 25-30 miles but even that wasn't until early August when I started training for my fall marathons.
