Yesterday I joined runners training for Quad Rock in running 15 miles up and down Horsetooth Mountain Open Space, my biggest outing since October 2019. It was lovely up there.
There's a lot of packed snow and ice on the trails and for lack of traction I was going very slowly on slick descending stretches like the shady parts of Towers and South Ridge. After I got home and ate I bought and installed some some cheap hardware to add traction to one of my pairs of trail shoes.
I followed the instructions on Matt Carpenter's screw shoe page and screwed 11 3/8" sheet metal screws into the lugs on the bottom of each Speedgoat. A 1/4" magnetic socket and a cordless drill made it as easy as advertised.
This morning I tested my shoe hack on a inclined patch of ice near my house and was pleased with the extra traction. I can run straight up and down the ice at an easy pace without slipping. I'm looking forward to trying these on my next icy hill workout.
