nah, this would have been way too long... especially with poison ivy involved.
No poison ivy on the 10K (at least I'm pretty sure there wasn't -- I did the 6K myself, but the 6K and 10K seemed to use more or less the same portions of the park). The poison ivy was encountered in the Sprint.
Yeah, just extra warm bridge crossings.
I actually chose a route because I thought it would have more shade...
