If you’ve managed to log at least 24,901 miles biking, you’ve covered the circumference of our little planet.

I never thought of it when I crossed the 25,000 mile threshold of miles biked, but this guy did and made it a goal.

Michael Marley, of Dallas, has completed his goal of cycling the circumference of the Earth or 24,901.55 miles. Marley started logging miles in 1992.

Marley, 51, of Dallas Township, recently accomplished a goal he has been working on for nearly 20 years – to bicycle the circumference of Earth in cumulative miles.
