I'm bound to run the Edinburgh marathon tomorrow. I still can't decide which shoes i should wear, Pegasus 34 or Asics Roadhawk FF. I'm aiming for a 2:40. Over short distances, Roadhawk are better lighter, but over the marathon i don't know, Pegasus feels much more comfortable and seems more responsive. What would you pick? Can you run that fast in the Pegasus 34? I heard some dude who ran a 1:06 half in them..
