It's been a while since I've challenged myself because I've been OK with my weight and fitness level, but it's one thing to be OK, it's another to be proud and confident.
I'm doing this because I'm inspired by some of the people I've been surrounded by - their indurance and motivation. I've also been inspired by myself. I know how to work hard, and use my will power, it's just been a while since I've shown that, so I'm making sure I'm still in control.
Good luck to everyone involved!
