t was a beautiful, sunny day in New York City as I rode my bike into Central Park. I took a deep breath and let it out slowly, pumping my legs hard to work up speed, excited to join the flow of other cyclists I expected to see on the six-mile loop road.But when I arrived, my mood plummeted. The road was filled with runners in a race while the cyclists were relegated to a single lane. I slowed down, annoyed, as I made my way onto the bike lane. Soon, though, my mood lifted: the cycling wasn't as slow as I had feared. I picked up my pace and got back into a rhythm, feeling my pedal strokes and paying attention to my breath.
