Most charity runs...while still challenging...have the advantage of staying on mostly flat ground. That's not the case with the Tapiei 101 race over the weekend in Taiwan.
Six thousand people race up 2-thousand stairs in the world's second largest building.
The winner got it done in just over 11 minutes. But Peng Huing Nian is the runner who will make you feel weak and worthless.
He raced up the building for the seventh straight year...and he's 94 years old.
He plans to keep on running until he's 101.
