Build the aerobic base
More easy mileage raises the engine that powers the whole race. Most runners stuck at a time are under-running their easy days and over-running their hard ones. Easy miles, done consistently, are the biggest lever.
Most runners chasing a faster 5K reach for harder intervals when the real gains are elsewhere. The 5K is mostly aerobic, so the levers that drop your time are base mileage, threshold fitness, and smart pacing, in that order. Here is how to actually get faster.

Tempo runs and threshold intervals lift the pace you can hold before fatigue takes over, which is exactly what a 5K demands. This is the most productive hard work for the distance.
Going out too fast wrecks more 5Ks than poor fitness does. Even or slightly negative splits almost always beat a hot start and a death march. Practice goal pace so it feels controlled on race day.
A faster 5K needs the fitness to show up late in the race. Film a hard rep, the AI flags where your form breaks down under fatigue, so the base and threshold work translate into a faster finish.

A 5K time comes down in steps as your aerobic base and threshold climb. The work is consistent, not heroic.
