Running zone

I actually hit my running "zone" this morning - it's the place where suddenly I feel like I could go on indefinitely and I don't want to stop. I walked my first half-mile today, then ran the whole remaining mile and a half! I haven't run that far without stopping since the last 5K I did over 6 months ago - and I felt better doing it today than I did then. Maybe it's my shoes that I'm breaking in for Walt Disney World.
