So, I am training for a half-marathon and yesterday was my longest run to date: 8 miles. I felt great while running and great after, but about 2 ours after my run I hit a wall. I went to an event yesterday and had to leave early because I was so out of it. I felt dazed, confused, and in general, just foggy. I kept getting in people’s way, and felt like I couldn’t form a coherent sentence. I didn’t eat anything before my run (which I never do); drank water before, during, and after I ran; and ate a veggie patty, broccoli, and some bread after my run.
On my way home I grabbed a chocolate milkshake and spent the next two hours on the couch. Then I felt normal. So my question: How do I avoid this next time? I would like to not be a zombie or have to drink chocolate milkshakes after every run. What do I need to add? Gatorade? More food? Any help would be greatly appreciated!
