Threshold is the main lever
For many runners, better 10K performance comes from raising sustainable pace, not adding more all-out speed.

Training notes
Make the plan fit the runner.
Long runs still matter
Aerobic durability helps goal pace feel less fragile late in the race.
Practice race rhythm
Short race-pace blocks can teach control without making the workout a full 10K race.
