Last year i wrote a thread as a 16 43 5k runner and asked about the chances of a (17 year old at the time) breaking into 14 flat. People said that breaking 16 or 15 even was unlikely. I have been running for 2 years now and have a 15:45 5k and a 33:05 10k. I am running 40 mpw and have had limited injuries, (some minor setbacks). I want to ask the forum, now as an 18 year old, if i start running some serious mileage something like 60-70 mpw avg could I be in striking range in a couple of years? (no im not a woman)
