I am 47 years old and my PR is 3:02--which was last year in my first marathon. I qualified for NYC 2016, and so I ran it. I felt great through the first 20 miles, truly thinking I had a sub-3:00 in the bag. I was 1:28:37 through 13.1, and cruising along First Ave., smiling and feeling very much in control. I get to the Bronx, and start feeling pain in my quads. The pain got worse with each of the final miles, and then my hamstrings, at about mile 23, joined in the pain party. What is really strange about this is that I NEVER get muscle pain during a race--never. I was shocked when it started happening. I got a slight twinge at about mile 23 at Richmond last year, but I slowed about 10-15 per mile, and felt okay at the end. In New York, I felt awful in the last five miles, seeing my first 8-minute splits in ages (over the last 3 or 4 miles). I ended up running 3:04. No sub-3:00 and no PR, either.
I have a good friend who is a very knowledgeable and accomplished runner (25 marathons), and she thinks I should try a back-to-back, as long as it is two weeks away (not one week). I can still get in a race not far from here on Nov. 20. She thinks most of my problem stemmed from being away from home, standing line for hours, and having different nutrition. I gather I had cramps? The pain was pretty bad. Again, I have no experience with this type of pain.
What do you think?
