Distance Running Economy
Eight weeks of stiffness, cadence and hill work aimed at running economy — the same pace at a lower cost.
How to run it
- Economy improves through strength and stiffness, not extra miles. Mileage stays flat for all eight weeks on purpose.
- Heavy strength twice a week does not make distance runners slow — it makes each stride cheaper.
- Hill sprints are ten seconds, fully recovered. They are a power drill, not a workout.
Springbak® note
A 5K is roughly 2,500 ground contacts per leg. Install Springsoles under your trainer insoles at the week 1 time trial and use the same setup for the week 8 retest.
Shop SpringsolesThe goal
Improve 5K time by 30-60 seconds without increasing weekly mileage.
How it progresses
Phase 1 · Weeks 1-3
Cadence work, strides and heavy strength twice a week.
Phase 2 · Weeks 4-6
Hill sprints and threshold work, mileage held flat.
Phase 3 · Weeks 7-8
Sharpen with 5K-pace intervals, then retest the 5K.

Questions about this block
Will lifting make me heavy?
At 4-6 reps with long rest you build force, not size. Keep the volume low and the intent high.
Can I race during the block?
One tune-up race in phase 2 is fine. Replace that week's threshold session with the race.
