Basic facts: I'm 23, 5'11", and 12st 6.5lbs (79.151 kilos) I've been practicing for my mile and a half on the ADSC/BPFA (whatever it's called these days). Living in sunny Sheffield, which is more hill than fields, there's not exactly a lot of flat land round here, in fact come to think of it, I can't think of any roads nearby which aren't on hills, off the top of my head. So I've been running a route, it's not a long route, it's 1.09 miles, but to make up for the shortfall, it's nice and hilly. Down a long shallow hill, up a steep hill up concrete steps, along some grass for about 400m then down another long hill before running up a couple of medium hills, then back down a shallow hill and a nice flat to some some steep steps and another shallow hill back to my house. Running surface (apart from the very start/finish is gravel or grass. Anyway, my running time on this minuature course when I first ran it was (cover your ears) 16:24. Over time it's slowly and painfully come down, first to 14 minutes, then 12, then 11. With this time on the short hilly circuit, my time on the longer (a true 1.5 miles) but much flatter circuit at the "pre-ADSC" weekend assessment was 11:27. Enough to just scrape a pass there. I've managed, the past few runs, to get my time on the hilly circuit to around 9:50, 9:55, 10:05, and my recovery time from each run has become shorter and shorter. With each run I spend less time sat under the shower feeling sorry for myself . But now my run times have stopped improving, I seem to have hit a 9:50-10:05 plateau, and I don't seem to be able to get past it. I'm eating and sleeping okay, not eating rubbish or anything, running 3 times a week as a minimum. Is it just a case of pulling my finger out, or am I doing something wrong?
