XC ski at Elm Creek, skate style on old rentals (that haven’t been waxed in about 2 years?).
I THOUGHT I was taking it nice and easy. But as soon as I stopped, I felt a bit nauseous. I haven’t used my arms much for anything lately, so this is a big wake-up call for my Birkie training.
Counting the miles as running miles. Not exactly the same training effect, but close enough. Tougher in some ways than running the same distance at the same pace.
