A first 10K is long enough to reward consistency but short enough that most runners do not need extreme mileage. The plan should make easy running feel routine before it makes workouts feel impressive.
A simple weekly shape
Use two or three easy runs, one gradually longer run, and at least one full rest day. If you already run consistently, add short controlled pickups or a light tempo segment once your easy volume is stable.
Build the long run slowly
Extend the long run in small steps and cut it back periodically. The goal is to finish most long runs feeling that you could continue, not to race every weekend.
Race the first half patiently
Start at an effort you can control, especially if the field and atmosphere pull you faster. A steady first half leaves room to increase effort when the finish is close.
