The Tale of Two Runs: 15 Miles vs. 13 Miles

Don't worry. Reading this post will be a lot faster than reading a book! It was only a difference of two miles, but what a difference in how I felt for the two runs! 

Monday, I planned to run 16 miles, but since the end of my run turned into a "rest on a bench/run to the water fountain/rest again" workout, I called it a day at 15 miles. Maybe I was low on electrolytes because I was only drinking Powerade instead of a GU tablet dissolved in my water. I also ate some Fig Newtons, dates and potatoes.

Friday, I ran a much easier feeling 13 miles. Yeah, it was 2 miles shorter, but I felt so much better. During my run, I had a GU electrolyte tab, a vanilla GU gel and a salted caramel GU gel. Maybe gels are better utilized when my body is heat-stressed. 

A lot of times, we'll have a tough day and then the next time that we do a similar workout, everything's better! It may have been what I drank and ate, the fact that I was low on carbs the day before Monday's run, that I wasn't trying to push especially hard at the end of the 13 miler after such a hard 15 miler or that Monday was just an "off" day. I hope your runs this week are more like my 13 miler!

Caffeine: The Performance Enhancer in Your Kitchen I've started drinking coffee before key runs like the 15 and 13 milers this week. How about you?


  1. I had a similar experience. I'd never felt so bad after last week's 15 miler as I did that day. I was so dizzy I could barely walk. If I was racing it would've been a DNF for sure. This week was SO much better. Turns out I got sloppy with my fuel and simply didn't take in enough calories. I should know better.

    1. I don't think I ate enough either. Live & learn!

  2. Great point that sometimes two similar runs can feel so dramatically different. I've had that happen several times in training, often in the same week just as you did.

    I also loved 0.03 seconds - what a great article!

    1. It was a good article! I need to read it again!

  3. I think food/drink make a big difference in runs. I'm still loving your milage! I ran about that many miles in all of July haha - I'm going to check out that ROO interview. Thanks for linking!

    1. Sally's article on ROO - worth a listen!

  4. Isn't it amazing how differently two runs can go? Rest, fuel, and weather can all make such a huge impact on how we feel. Glad you ended the week with a better run.
