Total noob training for a Tough Mudder

[Sethum]

Well...I guess I've been slowly gaining weight since about 3rd grade. It would even out now and then but as I've stopped growing the weight just kinda stuck. I'm 20 years old and at my heaviest I weighed 280. I started "working out" and running an I am currently down to 230lbs. I have ran a few 5ks since starting to run but my favorite was the warrior dash. After I ran that I became addicted to obstacle course races and have signed up to do a tough mudder next year. Unfortunately next year the tough mudder are on the same weekend. I have decided to do both I want to be in the best shape of my life when I do the races that weekend. As far as guilds go I'm thinking a ranger as they are fairly good at everything but masters at nothing. Just trying to stay on track and get fit.
