Everybody wants to know what I’m on. What am I on? I’m on my bike busting my ass six hours a day. What are you on?  – Lance Armstrong
I am inspired by so many people, athletes and non-athletes alike.  Here are a few that I really like:

Jon Blais - The Blazeman
Jon completed the 2005 Ford Ironman World Championship despite being diagnosed with ALS, also known as Lou Gehrig's disease. I am a proud Blazeman Warrior...So Others May Live

Team Hoyt
Dick Hoyt is father of the millennium.  If you watch this and are not inspired, moved, and/or motivated, something is wrong with you. Really. Go get some help.

Jimmy Valvano's 1993 ESPY Speech
Don't give up, Don't ever give up

Ironman Video
There are 2 kinds of people, those that say "I can't" and those that say, "I can."

Fun Stuff ~ Triathlon Song 
I sometimes watch Bryan's (from Training Payne) video to make me smile and get me pumped for my next tri.

I first saw this over on Big Daddy Diesel's blog, and it really was inspiring to me.  Actually, he even wrote out the script on his entry here if you want to read it.
