I learned to skate by skating and by reading the rec.skate FAQ. You can imagine that my technique is not what it might be. Today I saw an oncoming speed skater vigorously swinging his arms from side to side, a great contrast to the casual fore-and-aft style I use or the more serious hand-behind-the-back. I tried the new motion and found that swinging my arms side to side counters the swaying of my body and lets me push off harder. Maybe I'll keep it up.
Today: 16.5 miles. This year: 918.3 miles.
