The Flickr blog has a blog post linking to a gallery of photos that capture people in motion using different styles, which I really like:
Capturing movement in our photos can be challenging, but it’s a great way to convey emotions. Here is a selection of some wonderful shots that capture motion in creative ways. To see more photos and share your own images, visit the full gallery on Flickr.
Here are two of my favourites:
