“Racin’ the Station” Duathlon is a Run/Bike/Run event where the participants will “race” the International Space Station (ISS) as it completes one Earth orbit. The ISS completes an orbit every 91 minutes 12 seconds. We will track the starting location of the ISS at the race start time and see who “beats” the space station by completing the event by the 91 minute 12 second mark.
Race Distance
The distances are in three “translations”:
geek speak: Run pi (km) / Bike e^pi (km) / Run pi (km)
global speak: Run 3.14 km / Bike 23 km / Run 3.14 km
old school ‘Merica only: Run 1.95 miles / Bike 14.3 miles / Run 1.95 miles
The run course is very flat (same for both legs) and the bike course has a few small hills, but is overall very flat as well.
