Just wondering if anyone thinks there is a distinct advantage to using spikes in a 5K or 10K on the track as compared to racing flats. I wear either the Kennedy's or Milers for 1500m, but I am thinking of using a racing flat for the 5K. The Cubatos and the new Nike (XC?) racing flats seem to be just as light, if not lighter, than most spikes.
Well, for the 10k, if it is your first 10k in spikes, wear the Nike Cross Spikes. As for the 5k, wear the milers, they are good for it. I've just always hated the feeling of soft, cushioned flats on a soft, rubber track: it's just not aggressive enough nor does it feel you can push off. Then again, if you are an extreme heal striker, flats aren't that bad of an idea.
either or. If the track feels hard go for the more padded racers. If the track feels soft it doesn't really matter, I like to wear spikes on a soft track.
