If you recall last week I ran 20 miles without carbs and crashed hard early in the run. I was thinking about that run and how I felt the night before and the day after, and I realized I probably had a little flu bug or something. I therefor decided to recreate the run today. I ate last night at dinner for my last meal. I didn't eat before my run this morning. I did pack gu packs with me incase I crashed like last week, but I didn't end up using any. I just drank water on the run. It was a much better experience this week.
I ran the same route as last week, and the first 10 miles I was 30 seconds faster, right at 1:14:30 for an AP of 7:27. Of course I did slow down on the second half being that I had no fuel, but nothing like last week. The second 10 took my 1:19:25, AP 7:55. I felt a million times better than last week and was not completely delirious when I got home.
Total run 20 miles, 2:33:55, AP 7:42
I definitely had some kind of bug last week. I don't think I'll be attempting the fuel free 20 mile run any time soon again though. It definitely is a tough run for those last few miles. Next Friday 24 miles... with plenty of carbs!
