I'm new to the forums but currently I can run a 39 minute 10K comfortably and an 18 minute 5K. Also a a mile in at least 5:30. I want to train for a sub 35 10K and sub 17 5K in a year (50 weeks)? I do about 30 miles a week at the moment already. Is it possible? What sort of training would be best? And are there any books/resources I can use? Thank you!
