That sucks!
It can be. You just have to alter how you shoot. You can't "machine gun" like all the Canon and Nikon shooters. You'll need to anticipate and just go for the few money shots. Look around the various Pentax galleries (here, Pentax Photogallery, etc) and you'll see lots of sports shots with the K100D series. The better high ISO performance will also help you.
Of greater importance will be your lenses. If you have some of the newer SDM lenses, your K100D Super can take advantage of that and the faster aperture will help greatly.
For close to $200, it's still a great bargain!
