Met an interesting fellow

After we arrived at Shanghai from Haikou, we bumped into a guy that was in the same race; he was from Mexico and has been in every Ironman race since he started 17 years ago; he was skinny but strong; according to him, he used to be over 200 lbs and chain smoked (since 11 years old). Now, he's doing Ironman everywhere around the world and had been interviewed by magazines. Sponsorship, of course...
