Today I set out to run 5 miles — my farthest distance since the marathon — and I was feeling good about it.
As I started running, I immediately felt “slow.” I was running under a 9:30 pace, which I don’t consider slow at all, but I felt oddly heavy compared to my mostly effortless-feeling pre-marathon runs.
Then disaster hit during mile 4 — a horrible, dreadful, crippling cramp.

I did a lot of walking during mile 4 to get rid of that cramp. It just wouldn’t go away! The last time I remember having a cramp at all was during a 15-mile run because I ate an unusual and insufficient breakfast beforehand.
After about 0.4 mi of straight-up walking, I resumed running and was able to finish out mile 4 and hit a nice pace for mile 5.
I’m 99% sure both the heavy feeling and the cramp were related to my post-marathon eating habits. I haven’t been eating unhealthily per se, but I have reintroduced grains and dairy back into my diet in a big way.
I’d say my marathon-training diet was loosely 85% Paleo. The other 15% consisted of candy corn, ice cream, cupcakes, etc. and anything I had out at a restaurant.
I never carb-loaded before runs — in fact, I specifically avoided grains, as well as dairy, for the sake of my stomach — and ate lots of protein (chicken, fish, eggs) and fruits/vegetables instead.
Now I eat… whatever I want! Grilled cheese sandwich with extra slices of cheese on the side? Sure! Pancakes for lunch? Why not!
My body is much, much happier when I eat little to no grain-based carbs or dairy, and I can clearly see that when I compare how I felt on today’s run versus how I felt before the marathon.
It was nice to have a grilled-cheese-with-a-side-of-cheese hurrah for a few weeks, but I’d much rather have enjoyable runs.
