Meb Keflezighi
Kara Goucher
Feet off the ground, long natural looking stride, high back kick, kind of floating in the air while moving along at 4:30-5:20 per mile.
Some of us look like this (me):
Yes, this is me at the 2015 Charlie McMullen mile race. At least my leading foot is off the ground and my rear foot is not completely flat. My arm position looks pretty good and body posture is okay, but not near Kara's or Meb's,obviously. And at the end of the mile I was a bit spent. I seem to be trying to suck all the oxygen out of the sky!
Here's another comparison, Jan at the same race;
Flopping hair makes her look fast anyhow. Both feet off the ground, that's impressive. Left arm crosses a bit too much maybe? Very intense expression, but that could also be that by her race a severe thunder and lightning storm was moving in with flashes near the track during the last 2 laps.
