Thanks for the welcome 
Shielsy - I'm from North Wales, just outside Chester. I've been running for just under a year. Running has helped me transition from a 17.5 stone pile of lard who's idea of excercise was lifting pints to a slightly smaller figure of just under 14 Stone. I still have more weight to lose (about 10kg more should do it), but now my motivation is more about getting faster times than anyhting else.
I've done about 7 10K events so far with times ranging from 0:55 to 1:08, all of the events have been resaonably hilly they don't seem to do flat races around here! I also did my first fell race on new year's day, it was crazy, 9.5km through mud, rocks, ice cold streams and very slippery grass banks, in my road shoes (a mistake I've now rectified with the awesome inov8 roclites) it took me 1:23 which sounds slow but considering my friend who does sub 35 min 10k took 55 minutes, I was quite pleased.
I'm aiming to do a minimum of 1 race per month this year, more if I can - I've discovered that racing is really where it's at for me I love doing them and it keeps me focused with my training.
I entered the Cardiff half last year but had to pull out because I stupidly damaged my right calf muscle by increasing my training distance too quickly, I jumped from training runs of 5-10K to runs of 10-16K and because the 15k runs felt quite good at the time, I ignored the gradual build up of stiffness in my right calf until one night, walking down stairs at home, there was an audible pop and excrutiating pain. It took me three months to fully recover, a mistake I really don't want to repeat.
On a more positive note, I did enjoy the longer runs and after my longest run of 16k I still felt that I had plenty more left in the tank so I'm quite confident that I can do the distance, but not so confident of reaching my target of sub 2 hours, but I feel that I must aim high though - otherwise I'm prone to lazieness! If I had to do a half tomorrow, I think I'd probably come in at around 2:15 so I need to shave off around 15 mins in 7 months.
My next event will probably be the postponed Blymhill 10K on 2nd March, also on the calendar are Wrexham 10K. Vale of Clwyd 10K, Bangor 10K and Abersoch 10K - I'm always on the look out for more races so suggestions are very welcome!
