Racing Iditarod
About 1,000 miles, or roughly the distance from the Washington Monument to Miami Beach. The course alternates every year between northern and southern routes. Odd years use the southern route.
Climbing Everest
The trek on the most common route, South Col, requires 7.5 to 8.5 miles of hiking/climbing from Base Camp to the peak at 29,029 feet. But it's not the miles, it's the altitude. The 1.5 miles from Camp 4 to the summit usually take eight to 12 hours.
