Claim to fame: Ultra-endurance athlete
Brendan Brazier is one of those people who does so much that just thinking about him will make you feel horrible about yourself. Sorry. He's a two-time Canadian 50km Ultra Marathon Champion, started his own line of plant-based products, writes books, etc. etc. etc. All done with plants only.
Claim to fame: Defensive lineman for the Chicago Bears
Carter is a 300lb vegan, and not the Prince Fielder-eating-a-lot-of-Cap'n Crunch kind of vegan. Of course, you could make some kind of joke about the Bears' defense and veganism, but we're WAY above that.
Now, none of this is to say that giving up your burgers will turn you into the next Tony Gonzalez (and gosh, we sure know how many great burgers are out there). So don't go thinking you can quit your day job and become a pro athlete if you quit meat.
