Ha ha here's hoping - thankfully no glasses to contend with! You sound like a seasoned pro.. how long did it take?
Me - a seasoned pro? Ha ha - no, not really. I haven't done any half marathons or anything like that yet; it still gives me a bit of a chuckle when I see people saying they 'only' went for a nine mile run!
How long did it take - well, I had to repeat plenty of weeks in the C25k, so it took quite a while to get to 5k. From then I gradually increased the distance. I've been running around two and a half years now and I'm at a stage where it doesn't feel like it takes too much effort and I feel confident doing it. I remember when I first attempted running: once or twice around my local block and I literally had to crash out when I got back home - my fitness was non existent! So then I decided something had to be done about it and committed to the C25k - the best fitness decision I've ever made. 
My current maximum is probably 10k, which is what I did today. The most I've ever done is 15k, but then I picked up a knee niggle which basically forced me to start from scratch again. Target for the first part of the New Year is to build back up to 15k, and then see where it goes from there.
Happy running, all!
