Hi

I'm Toby and I shockingly discovered that fat is out this season, to be replaced with some ridiculous thing called health, the new black, as it were.
I am 30 and currently 18 stone (even though I hate pies teehee) and I've been overweight for AGES. I've never had a problem with day-to-day fitness, in that I have always easily and willingly walked stairs, cycled to college and work, play badminton in a local league...But there's no other way of putting it, it's gross

Anyway in January 2012 I started one of those couch to 5k iphone apps, having jogged maybe once or twice in my whole life, probably because school made me. Obviously it's baby steps and easy going but I've not failed any of the sessions yet and can now run (jog?) for 20 minutes without stopping. By the end of March I should have completed the app (9 weeks) and therefore be able to run 30 minutes.
I've mapped out and measured my neighbourhood route by car and gps and it looks like I'll be running 3 miles in 30 minutes, if I continue at the same rate as I have been.
ok some actual questions!
I start to feel really tired/I need to get off now at about ten minutes, but I'm a stubborn b*stard and so I just continue and it kind of gets better or I just tolerate it well enough. Will this improve or will I always get this feeling quite soon into a run?
Also, I'm really not sure about how I should be feeling in general...I've used and abused my body so I'm rubbish at interpreting its signals, as bizarre as that sounds...I come away from every session with my ankles, calves, knees, thighs (and possibly hip, can't tell if it's just more thigh or what lol), my sides and back/shoulders feeling weak and sore...Will this get better (I'm sure it's normal for my body to protest at least to start with: wtf bro', just sit quietly and have a f00king family bag of Maltesers already). It's not a problem, I'm used to aches and pains, it won't stop me, but it would be nice to know that it will get better and won't happen so readily and that I'm not actually paving the way to injury (if I have to stop will I ever bother to start again?!)
I'm going to try and start some circuits that I've assembled from another app(!), things like weighted lunges/squats, and some core work, bicycle crunches etc...And I've got the 5k to 10k bridge the gap app (I told you I was lazy!) I'm just open to any comments/advice from the more experienced etc etc
Goals: Fitness. I would like to run the local Parkrun as a fun thing; I'd like to do 10k races for cancer charities although I walked 10k along the Thames today and it's flipping MILES!!

I'd love to get a really good time for 5k as well, but maybe the weight precludes this or the age? urgh.
Cheers
