I have recently re commenced running with the rather ambitious target of doing a sub 40min 10K next May. In the last 9 weeks I have shaved 4 mins of my time - currently just over 50 mins. Hence, a heck of a lot still to do.
I have reasoned with myself that I should be able to get 10% fitter and hence, this should equate to 10% decrease in minute miles - say from 8.00 to say 7.20 - obvioulsy over time, not overnight.
My question is this - say I drop 10% body weight, currently 12st - reduce to 11st. (I'm 5ft 8). Will the weight reduction of about 8% also mean I should be able to run on average 8% faster? Say knocking another 30 seconds from my average minute mile.
I am happy with my progress but just wondered what peoples thoughts were on this. I realise that reducing my weight means there is less effort required but does it work like that?
