I second this^
I never broke 14, but came relatively close and have many friends beaking 14 and 3 x mile at 4:28 or 5-6 x 1k at 2:48-45 with 600 easy jog rest is enough on paper.
I guess you do not wanna hear this, but tweaking your training, just getting a bit more endurance and resistence will get you there if you have the talent.
If I were you, I'd double 4-5x per week and do lots of shorter stuff like 10x300 at 48-45, 15x400 at 66s etc to get the pace feel comfy and not neglect threshold stuff like 2x5k at 15:30-15:00, 3x3k sub 9, 8-10 mile tempos at 5:20 or quicker, mileage not under 80 miles and usually not over 110, bc then the quality on the track might suffer. That's basically what the people I know do/did.
Example:
M - 5/8
T - 5/short track stuff
W - 12-13
Th - 5/7+short hills
Fr - 5/threshold
Sa - 8 / 5
Su - 13-15 progression.
