TK - are you new to the gym scene? That sounds like a good idea

I can do 500m in less than 2 minutes but cannot manage 2K in one go. I think I might do 4 sets of 500m with a bit of breathing space in between. i worked out my technique now, got my breathing and everything sorted just need to work on my stamina

Another month or two and I'm trying to do the 2k straight off - without feeling sick/not being able to walk afterwards

Not new as I used to go a lot about 14 years ago, where I'd combine running, with gyn work (weights work out) and rowing on the older style Concept II rowing machines. I got up to a reasonable standard for the rowing (1000m 3:17; 2500m 8:50).
I've been running quite regularly since about April last year, often lunchtimes around London. A couple of weeks ago, and due to the fact that the changing tooms in our office are out of action for about 10 weeks, I thought I'd join a gym. There's a guy who sits next to me who goes a lot to do weights sessions, and he introduced me.
Signed up on a 4 month deal, and have been alternating weights sessions (led by him) and aerobic workouts, mainly based around the Concept II (led by me). Have been pleasantly surprised that I can still get a decent enough tune out of the machine, despite such a long layoff.
I'm alternating routines on it, sometimes doing interval training at short distances e.g. 8 * 500m, sometimes doing longer stamina sessions, and sometimes doing pyramid sessions. Feeling all the better for it to. I'm hoping that combining this with the weights sessions will get me a lot fitter and with a better body shape.
I'm 44, about 6'0" tall and weigh around 13st 10lbs. Before I embarked on the running last year, I was 15st 1lb
Keep it going, and what may seem like little steps now will turn into big progress not too far down the line! I think you'll be able to do the 2000m straight off a lot sooner than you might imagine.
