I started running to deal with the stress of a very busy job. And slowly got addicted to the fun and excitment. So have not looked back since then. Enjoying the running (and also the life). I rely on websites and magazines . I have seen some good and useful websites from searching google. Just one little advice from my experience, don't hesitate to consult a physio once in a while.
Well done to date... 10k in 60 mins is a very good start.
It's important to take things steadily and not try to do too much too soon.
Try to do 4 runs a week.
1. A long slow run...for now say 6 miles.
2. A speed session..say 8 reps of 50 metres with jog recoveries in between. After doing a warm up of 10 mins first.
3. A steady 3 mile run.
4. An easy 5 mile run.
You could do this for a couple of weeks and then gradually increase your mileage...no more than 10% per week. Also don't increase your long run by more than 10% per week.
Best advice though...find a running club to join. It's easier to run with others!
