OK fellow Grovers, talk me off the ledge. I just finished a 15-mile run as part of my training for the Flying Pig Marathon. It was freaking hard! I'm just having a hard time wrapping my mind around doing that PLUS 11MORE MILES! My only saving grace here is my training runs (including this one) are all very hilly. I'm 42. I ran the Half last year, thought it was easy. I average about 10:15-10:20 per mile. Tell me I'm going to make it. Did anyone else feel like this their first time?
