Totally forgot to mention in my last post that Colin and I both found stuff on our last long run.
One of our runners found an unopened Cran-Razz Clif Shot Bloks (Colin's fuel of choice). I said I'd carry it until I could ask if it belonged to anyone running with our group, but there were no takers. Since I had it in my pack for about 22 of the 24km I ran I figured it was mine to keep.
When we got to the car Colin remembered to tell me that he found a Nathan fuel bottle (from a belt) on the trail. It had a few rocks in it, but nothing that couldn't be washed out. He's excited because it's an 8oz. bottle and fits perfectly in his bag's pocket.
Hopefully these didn't belong to the same runner! I'd be choked if I lost either of them. What's the best thing you've found on a run?
