So this is where i'm at!!

Firstly hello to you all,
 
I'm 32, been unfit most of my life and i've just given up smoking! I've made attempts to give up before and get fit, but have failed miserably, This time it feels different, i know some of you have heard this before, but it is!
 
I think sometimes things happen or something just clicks, well my trigger was the loss of my 16 year old step son! He was killed while out jogging from his girlfriends, he was training for a half marathon in may! He was with an professional football academy and his fitness was second to none, he would think nothing of getting his trainers on and running 10miles, i used to take him everywhere for football, we grew very close over the last 5 years, I never saw him as my stepson, he was my son! The funny thing is he never had a great relationship with his real dad, we used to talk about this alot, his dad is trying to make out he was the greatest dad in the world etc etc, but he watched him play football a few times in the last 5 years, and his girlfriend and his friends know that i've kept my head down and let his dad have his moment, because at the end of the day he is grieving as well, They messaged me the other day and said they didn't know what his dad was going on about, My Boy used to talk to them a lot about us and he said he saw me as his real dad!!! I was so touched by that!!!
Anyway, I'm doing the half marathon in may in his honour! and i will get fit, thats what he wanted me to do, god knows he used to keep on at me about it!!!!
 
So this is why i'm here, i haven't got a clue, i really haven't, i don't know where to start, i'm fussy with food, i don't know what to do with exercise etc etc, i'm just running, cycling and on the multi gym at home, i can't afford to go to the gym,
 
Like i said, i'm 32, 5ft 9" , about 15st
 
I hope you theres some one out there that can help!!!
 
If theres anybody from herefordshire, that can meet me and give me any help, that would be great!
 
Great Forum by the way!!!!
 
Regards
 
Will

Welcome to MT, You need a plan, a structure for both your diet and your excersice, a good starting point is to look through the articles on here, there free and the advice is good. It is worth siting down and outlining a plan, i am not a runner but i know you need a progress plan, so take the date of your run, you already know the distance, and work backwards to today, and put goals in for a distance you can run each week, and increase the goals on a weekly or bi-weekly basis so reach your main goal. You need to eat right, your eating is at least 50% of reaching your goals. Once you have a plan, and a diet, post it back on here for people to share their views with you.
