Vicky I have just started running again after a 6 year relaps into my old eating habit.
I am just under 20 stone so I know how you feel about progress.
There are many factors about your running which wil come into play.
Ok your running on a running machine yer?
What speed are you starting at and what do you get to?
Although a heavy runner, just lost 5 stone and been back swimming for a couple of months and running for a month. Currently doing around 40 minuites run at 8.5 to 9.5 towards end. Please note I've always been active even at 25 stone.
Trainers, wow I have spent hundreds on trainers in the past. I tend to lean towards New Balance as they do a wide fitting but my current pair were bought from sports direct and are ??30 new balance. There great. I am having some issues with my calf after 30 minuites but I think this is my style.
I do a short stretch to warm up then I do the low impact air running machine for 30 minuites, then a cross trainer for 15 and then into the run. Don't get me wrong I am drenched when I finish.
As in breathing correctly, wow I am a nightmare when I run, I often aware aloud which is not a good thing and I grunt sometimes.
Don't be tempted to go to fast to quick. As for setting goals I do try to but end up just doing my own thing.
The one thing is a must...... Keep it up...... Your cool down stretch should be held a bit longer and is very important.
