From the Montana Kids web site, we have a camp out in Selway-Bitterroot Wilderness. They say
The Selway-Bitterroot Wilderness, covering 1.3 million acres, is part of the Bitterroot National Forest, Clearwater National Forest, Lolo National Forest, and the Nez Perce National Forest, lying on both sides of the Bitterroot Range. Its boundaries are between Montana and Idaho. It includes large parts of the Lochsa and Selway river drainages.
I did 5.3 miles today, on the indoor track. It felt smooth. It wasn't remarkably fast, but it just felt like a good, strong run.
