For those of you who are new around here, I figured it would be a good idea to fill you guys in on a little City Coach history. Back in April 2004, City Coach co-founder Christopher Bergland set the world record by running 153.76 miles in 24-hours on a treadmill. To this day it is the most amazing and humbling athletic accomplishment that I have ever witnessed.
On a diet of Pedialyte, Ensure, and just about anything else he could tolerate, Christopher ran continuously for a full day, only stopping for occasional bathroom breaks (during which the clock kept running.) He averaged 9:21.9 per mile for 24-hours and beat the record with just a few minutes to spare. Dean Karnazes, who was alongside and also shooting for the record, finished with 147.96 miles.
Details of the effort can be found in the Kiehl's press release, as well as at the Chapman Logic blog. As you can see from the chart below, Christopher's best hour was good for 7.27 miles, and in the 24th hour he was still going faster than 12:00/mile. In fact even his last marathon of the day took just over 4:30.
