All the same, I think I wound up on the edge. I had the Built bar; and ate a GU-Gel at my turnaround point. Next time, I’d better take along more to eat; what I had with me was barely enough.

Yesterday I did some 5-minute efforts at pushing the pace to 14 mph or more; and that got tough when the path turned and I had a headwind. I did two of these intervals on the way out; and one or two on the way back. My efforts fizzled during the final minute of the last hard effort; and maybe I was already on the edge by then.

Hard efforts like that burn up your fuel faster; and with about three miles left to go, my legs suddenly got an odd, weak feeling. All I’ve read about bonking nudged my mind; and luckily I had one piece of bar left. I knew I’d better eat it, even though I didn’t feel hungry. I’m glad I didn’t cross the border!
