The Tendai monks believe that enlightenment can be achieved during your current life, but only through extreme self–denial.

For the Tendai, the ultimate act of self–denial — and the route to enlightenment — is a physical challenge known as the Kaihogyo. Because of this challenge, the Tendai are often called the “Marathon Monks.”

But the Kaihogyo is much more than a marathon.

 The Kaihogyo

The Kaihogyo is a 1,000 day challenge that takes place over seven years.

If a monk chooses to undertake this challenge, this is what awaits him…

During Year 1, the monk must run 30 km per day (about 18 miles) for 100 straight days.

During Year 2, the monk must again run 30 km per day for 100 straight days.

During Year 3, the monk must once more run 30 km per day for 100 straight days.

During Year 4, the monk must run 30 km per day. This time for 200 straight days.

During Year 5, the monk must again run 30 km per day for 200 straight days. After completing the fifth year of running, the monk must go 9 consecutive days without food, water, or rest. Two monks stand beside him at all times to ensure that he does not fall asleep.

During Year 6, the monk must run 60 km (about 37 miles) per day for 100 straight days.

During Year 7, the monk must run 84 km (about 52 miles) per day for 100 straight days. (52 miles per day!) And then, he must run 30 km per day for the final 100 days.

The sheer volume of running is incredible, of course, but there is one final challenge that makes The Kaihogyo unlike any other feat… (more…)
