With the damp and chilly weather outside, participants in Vienna's first indoor marathon were led to expect more favorable conditions on Sunday. But the race turned out to be far easier than they could have imagined.
"Zero incline or descent, no wind and a constant temperature of 15 degrees Celsius (59 degrees Fahrenheit) allow for personal best performance," organizers promised on their website. And there were plenty of personal bests for the some 850 runners who signed up for the race -- though it was for a different reason entirely.
The course set up through two large halls at the Austrian capital's main convention center turned out to be some 1.8 kilometers (1.11 miles) too short. Instead of running the standard marathon distance of 42.195 kilometers (26.2 miles), runners clocked just 40.435 kilometers.

That has to be the worst marathon idea ever.
