Alright chaps just a quickie. As advised by rab in another topic i measured my running distance online using the measuing tool on google earth. Bloody good program it is to, i found that ive been running 1.74 miles instead of the 1.5 i had thaught it was. Last night i ran the 1.74 miles in 10 mins 36 secs, but its not 1.5 miles. Im just wondering if someone could explain to me how this would be worked out. I.e. how do i scale it down to what the time would be if i was running 1.5 miles? How many seconds do i take off etc? Would be much obliged if this could be explained to me for future reference as im proper crap at maths.
