I have been getting back to a little treadmill running this month since we're staying in a complex with a gym. I haven't run indoors or out for over a year, so I'm taking it slowly. Today I did 3.5 miles total, 1.5 of that was running at a slow 11-minute mile pace, and the rest walking on a slight incline. It was nice to do that after a 40-mile ride yesterday and have nothing hurt!
