I've been running for about a year and was looking for ideas about what to do with my training. Right now I run about 10-20km per week, mostly on steep hills. My longest runs are hilly around 10k; I do them in around 1h20m.
And I can do a 5k on the flat in around 23 minutes it seems.

However, the site's recommended mileage for beginner runners, posits that you do at least 15 miles per week, which is beyond my current mileage. Hm. However my 5k times indicate that I should be doing something like the intermediate program, though.. the mileage seems far too ambitious.

Should I really build up my volume like that? I was thinking of just ignoring the volume on recovery days and focus on the main workouts
