You could try doing some strides or a bit of genuine fartlek: without the watch and making it fun. Here's how you make it fun: ring somebody's doorbell 5 times at 6am and then run:)

I'm working on a theory called "Post-Marathon Depression." I haven't had you on my couch, but my preliminary diagnosis is that you are suffering from it.

I did a few fartlek runs that weren't any specific distance for each interval (though I think they were in the 9-10 mile range overall, but they don't have to be long), but I lapped my watch for posterity when I felt like it. Any interest/access in/to trails? Now that I am back to using my iPod, I sometimes play a game called "spring the chorus" (you get the idea).

If that fails, try Bam's idea, which I like very much.

Thanks for the suggestions guys - think I will stick with the more conventional approach Bam.

I had actually run out of iron supplements and the new supply is just starting to kick in.
