Plein air painting, while not officially a sport, is a good workout. First you have to pack your backpack (paints, thinner, brushes, palette, canvas panel, towels, garbage bags, clamps, bungee cords, sunscreen, hat, collapsible umbrella, water and a power bar) and your easel (in my case, a "guerilla" box and a tripod) and then drive to your previously scouted location. Then you either "car paint" if your vista is viewable from the side of the road or you hike. And then you stand for a few hours, stepping back and forth to check how the painting is coming along.
So, if you see a painter on the side of the road while you are out for your run or ride, wave or say hey. We sports people need to stick together!
