Long Term sub 16 plan?

How old are you? Are you a kid who is still growing in high school, or are you a fully grown adult?

I'm 20 so I guess that classifies me as a fully grown adult.

Hard to help off of such a vague training plan. Off hand, I'd suggest not dropping your mileage in season. At least not until the very end. Add intensity to volume.

Doubles could be a big help if you're not doing them already. I've noticed that fast twitch guys seem to respond especially well to doubles.

O I'll try to be more specific well what I do is for base just run steady mileage, like 6:40-7:00 pace usually if I feel good I might cut down to 6:15 or 6:20s by the end. Then two months out I drop mileage to around 55 or 60 and add in workouts. The workout my week revolves around depends on the race. For example for a 10k, Ill do 10k pace work as my main workout and then a tempo and some shorter stuff (400s or 600s). Then I taper off for a week. This is how I've got all my prs. I try to peak 3 times a year. O and I'm pretty sure I'm a slow twitch guy. There is a reason I didn't post my shorter prs. But here they are in case they're relvant. Mile-4:58, 1000-2:55, 800-2:16. I never peaked for any of those they were all run during my two month period before a big race. i would sometimes replace short workouts with short races.

At 20 you're not there yet. Physically you'll continue to mature reaching your peak at 25-28.

You're a pretty decent runner but you need to work on getting your mile time down under 4:40 and your two mile down around 10 flat. In short, you heed a track season. Like all comer meets during the summer.

Your overall mileage is fine.

You don't need to go hog wild with speed work but the ability to run 3 x 1600 in around 5 minutes with an equal recovery (5 minute jog) would help.

Or

6 x 800 in 2:30 with a 400 jog...or 4 x 1200 in 3:45 with a 600 jog.

A sub 16 is equivalent roughly to a 26:30 8k or a 33:20 10k.

You need to change your base phase to start adding some actual workouts. Just running is good for general endurance, but after doing it for a number of years start adding in stuff.

Like start adding in fartleks, hills (or hill circuits), easy long intervals, tempos, etc.

Really periodization shouldn't be dramatic shifts from period to period, but a gradual inclusion of elements until those elements take priority (like start adding in a short set of 400s before specific phase on the easy days to get your body used to the shorter efforts when the time comes that you do exclusively short track work)

Peter and Sebastian Coe and Renato Canova are big proponents of touching on speed throughout the year, so try throwing in some short hill sprints, 30sec or 200m reps or whatever at the end of easy days year around

given your times you may want to take your easy days slower around 7:30s. That way your workout days can be of higher quality while you are still getting your mileage in.
