How long would it take you to run around the world?

Nowadays, marathon lovers have taken a step higher in their marathon. 21km and 42km is no longer the limits. Human strength has gone beyond the limit.

However, have you ever wondered how long it would take you to run all around the world?

Theoretically speaking,  calculating the Earth circumference using the formula of 2*Pi*r would result in the Earth's total length of about 40,030 km.

Now is up to you to decide the amount of running per day. If you run a marathon 42.2 km per day, you'll be done in around 2.5 years.
