This weekend will be the first CX race in mud so far this year. Everyone seems really excited for the mud, but I'm dreading it. Any experienced folks have advice for racing in foul weather?

I have heard some folks talking about pulling out the toe spikes. Does anyone here use them? Are they a necessity? I'm trying to stop spending money on bikes in 2009, so I don't want to have to get a different pair of shoes unless I absolutely have to.

Thanks!
