JRP- It was cold. ~16°, windchill 3° to 5° below. But the air was clean and clear and the sun was shinning. Any colder and I'd need my ski gloves and balaclava or face mask.
BST to Red Butte and back. A nice day. We ran a slow and ez pace. About mile 8 I hit some ice and fell flat on my back. Falling in such away means your feet and legs don't get hurt.
