Daffonce - We'll definitely have to meet up for a workout for sure. Ive got a long way to go to catch up to you, but at my highest I was north of 380 so Ive already made some good progress.
Mwchandler21 - Welcome!! You wont die, I walked a few 5ks at the end of short triathlons last year and got through it just fine. I was tired and sore, but I did it. And you can too!
