Got out on the new bike today. Felt like I was invincible, and flew up the riverfront trail about 6 or 7 miles before turning around to return home. Then it hit me, why it had been so effortless: the tailwind, now the headwind. Coming back was miserable, but I still averaged somewhere around 15 mph (very rough estimate) on the trail.
In hindsight, I should have known something was awry when I could smell the hops used by that little brewery in Soulard all the way from downtown.
metrics distance: 15ish miles time: about an hour (no computer yet)
