30,000 to Run Disney Half and Full Marathon

Three thousand people will run both races, which are on Saturday and Sunday. I had no idea this race had gotten so big. 101 Dehydrations? My memories from running it in the late-1990s include waking at 3 AM EST (2 AM my time) and taking a bus to the park, where we stood in the dark for hours. The course had lots of concrete highway ramps.
