2 mile walk around Centennial Park today

I was pretty pleased with my walk today: 2 circuits (2 miles, 3.2 km) around Centennial Park in Helena. The last couple of times I had walked there, at the beginning of this year, I was only able to do a half mile, and I was having to stop a few times to catch my breath. Today, I stopped after the first circuit to have a drink but otherwise did it in one go in about 55 minutes. It was very cloudy and the temperature was in the low 70s °F (about 22 °C) with very little wind. I clocked up almost 5,000 steps, which is a good starting point from which to measure future progress. My plan is to do this weekly, going faster and/or further each time.
