Born to run

I just finished reading the book recently.  It's a fun book about running.

The book is about ultra runner, a secret Mexican original group, and some ultra races.
The author tracked the mystery running man in a canyon in Mexican famous for ultra running (forget the name). He visited those people and met a guy who want to organize an ultra running race between American elite ultra runners and the Mexican tribe men.

In this book, he also discussed the "born to run" of human body, from both archaeology and evolution's perspectives. Some professors found that the human body was evolved to run long distance, human's brain and reasoning skills etc. were developed during hunting animals by chasing them down over a long distance.  That's a really impressive discovery, but I believe so as I am a runner too. :-)

It's fun to read the book and get inspired by those ultra runners.  I may run an ultra marathon like 100k sometimes this year or next year.
