How are people running so fast?

On today's running podcast or the shakeout podcast, as we've originally named it. We touch on the recent track and road races, that have been pretty decent to say the least. So many records over the past weekend. Most impressive would be the 57:32 half marathon World Record, which probably for the wrong reasons brings a lot of attention to the sport.
