24hr races are gnarly. I did one on my ss mtb when I was racing, it was tight. I also rode light, easy single track trails on my first fixed conversion. I had it set up with knobby cyclocross tires. I ended up breaking that frame though at the bb shell.
I'd rather mash trails on a ss thatn fixed but it's still hellsa fun fixed and for sure do-able if you know how to ride your bike.
