So, after finishing up my 3 legs I volunteered to run Wei's final leg since he had picked up a knee injury. It was a 7 miler with a couple of steep climbs but I felt pretty good about it since it was easier than my last leg and I had felt pretty comfortable doing that one.
I started out strong and was feeling pretty good until somewhere after the 5 mile mark. That's when I suddenly and abruptly lost energy, I started feeling dizzy and I didn't have any strength in my legs. I was able to continue running for another mile and a half or so and then I had to walk the last half mile. I made it to the exchange with Joe and promptly crashed. I lay down by the side of the road and it took a huge effort of will to get back up 10 minutes later. My awesome teammates helped me to the van and fed me a steady diet of sugar and electrolytes while I tried not to pass out. I finally managed to make it back to the land of the living by the time Joe had finished his leg (well ahead of time as usual).
