I was reading the RW interview with Mara Yamauchi in which she states... "The longest I've run is a hilly 23 miles so I count that as 26"
This came across as a really odd thing to say, I thought 23 miles was 23 miles no matter where it was done, or am I mistaken. Should I starting counting 23 miles as being 20 miles on a treadmill because its easier?

Im really curious to know what more experienced runners than myself think regarding her statement, do you change what you consider to be your distance/time based on effort, percieved effort or surface you are running on and if you do is there any calculation used for the adjustment?
