Hey guys, this is my first post here and I would appreciate some advice.
I am 19 years old and not in terrible shape, however the last 2-3 years have been solely me working a part time job and sitting on my butt playing on my computer all the time...
Anyway, after the buzz of the olympics I was inspored by the triumphs of the likes of Ennis and Mo, and decided to get fit and back in good shape. I started running 4 weeks ago and once I bought all the shiny new gear that I wanted set out on my first run. Luckily for me I live right by Langley park so I had a nice place to go for my run.
I spent 5 minutes walking there and then jogged/run for as long as I could, well that was the plan. After about what felt like 20 minutes but was in fact only 1 I was panting and huffing. I couldn't believe how unfit I was.
I kept at it and decided to get a 0 to 5k plan on my iPhone, and have been following that closely. After a holiday to Bournemouth a week ago I found it was getting really easy, really quickly. Even though I am going extremely slow.
I decided to speak to a friend who runs ultra marathon's and see what he suggested. He told me to ditch the phone app and go for a jog, but go as long as possible at a medium pace. Suprisingly I ended up doing the full 4k circuit that I was supposed to be doing at week 7 of the program, but 3 weeks earlier! Well chuffed!
Sorry for tha long wall of text, just had tho tell someone 
My question is, if I can do the 4k route, should I ditch the phone app and do the 4k route again and again and slowly build it up? I have a ParkRun (Black Park) 5 minutes walk away from me too, and that is my main immediate goal. To finish a 5k race. I know parkrun isn't a race but if I can do that I can register for a proper race.
I am contemplating registering for this Saturday's ParkRun and just trying to finish. Do you think this is a good idea? or should I be improving slower? I am feeling no pain or injuries, but when I get home after a run I often have a small tickly cough, although I have heard that is because of my mild asthma.
I look forward to hearing any advice,
Cheers!
