I got septic tonsilitus and feel like Sh!t, you know i will complain all the way around peel park don't you, LOL, but give me a few days and you got a deal! *i am on the sick now for a week from work*
If you are looking for a flat start but away from people, you could always try the Radcliffe trails.
Radcliffeac has a beginners group run by a friend of mine as well. It gives you the push to get out of the door on those dark evenings. At this time of year we obviously stick to the roads though.
Holcombe hill is a good one to try to acheive as it is quite steep but good surface up a dirt driveway but you have a sense of acheivement reaching the top.
I got into this after years riding bikes. I thought i would do the New years day fell race because it was something different to try. My line of thought went- it's only three miles it'll be a laugh. I don't remember laughing! I was going up and down stairs sideways for a week afterwards!
