We have a rec complex surrounded by a half-mile long asphalt path. Once the outside temp reached 20 degrees I headed to the rec center. They have an industrial-strength snow blower that scrapes the asphalt creating berms up to 8ft high. When weather allows I park my truck along-side the path so I can grab water without having to leave the path. With all this snow I had to park in the lot. I walked the first lap to check for crusty snow hiding black ice. About 70% was open and the rest spotted with ice and snow. Too much for running.
In my truck I keep a backpack with a 20 kilo weight inside, put it on and started walking the path.
I learned decades ago that my left leg points straight ahead while walking or running. But my right leg points about 15 degrees outward. Today I realized when stepping on ice my right leg rotates clockwise another 15 degrees. After three hours I'd slipped several times, not falling but straining most of the muscles around my right hip.
Done on the track I headed to Ace Hardware to buy 1/4 inch hex head metal screws. I have shoes already embedded with screws but my wife has packed them away. So I bought more screws for my new shoes. Without mounting screws into the soles, I can't run on ice.
I was on the path for 3 hours, guessimate I did about 9 miles.
I've been doing a lot of core work. It's paying off as the backpack didn't bother me at all. In years past I would constantly need to adjust or use finger tips to take the pressure off my shoulders.
Only two more months of winter.
