Face it, almost every coach would be able to make Newbury Park a top team if they coached there. Brosnan isn't an exceptionally good coach, he's just an exceptionally lucky one.
You can reach 99% of your potential just off a generic training plan. No secret workouts, no mental tricks, no elaborate pre-race rituals. Just don't do anything stupid like attempting to go from 10 to 80 mpw in a month.
You can easily fit an entire training plan for the 1500 through the 5K on less than one sheet of paper. Just keep things simple:
Base phase: ~4 months
Monday: 7 mile long run
Tuesday: 4 miles easy
Wednesday: 4 mile tempo run
Thursday: 4 miles easy
Friday: 4 miles easy
Saturday: race(s) or time trial(s)
For Monday-Friday, add an additional mile to the run you did 7 days ago. Cut mileage in half every fourth week and go back to where you left off after that. Do a few strides after the easy runs.
Competition phase: ~2 months
Mileage should be two-thirds of what it was during the last part of your base phase. Replace Wednesday's tempo run with a 1600-1200-1000-800-600-400-200 workout. Run those distances with nearly-full recoveries at 90-95% effort.
To taper, cut your mileage in half two weeks before your key race. Replace Wednesday's workout with a 4x400 done at race pace with full recovery. Take a week or two off at the end of the season and repeat.
Training isn't rocket science. The program above with a few minor tweaks is really all you need to get to within a few seconds of your genetic potential.
