Unfathomable, I have marathon friends who run a marathon every month. I thought that was crazy.<p>Before this guy, I thought these monks were the ultimate in mind-and-spirit-and-body physical endurance:<p>> Only 46 men have completed the 1,000-day challenge since 1885. It takes seven years to complete, as the monks must undergo other Buddhist training in meditation and calligraphy, and perform general duties within the temple.<p>...The final two years of the 1000-day challenge are even more daunting. In the sixth year they run 60km each day for 100 consecutive days and in the seventh year they run 84km each day for 100 consecutive days. This is the equivalent of running two Olympic marathons back-to-back every day for 100 days.<p><a href="http://www.howtobefit.com/tendai-marathon-monks.htm" rel="nofollow">http://www.howtobefit.com/tendai-marathon-monks.htm</a>
