If you are new to running just concentrate on easy running (conversational pace).
If you want to up your mileage, limit it to 10% extra per week.
Don't try and do too much too soon.
I didn't start doing, speed work, tempo work until I was well into my 3rd marathon.
If you feel like you are doing too much too soon then have a cut back week (reduced volume)
