How did you like the spikes?
It was a great feeling to be able to run on wet and muddy stuff without falling! The only thing I regret is that the spike shoes are sort of like orienteering shoes in that they don't have much cushioning and have a rigid back to the shoe. For races less than half an hour long, I think I should be ok, but I would worry about wearing these spikes for more than that because they'd give me blisters.
