Building an Aerobic Base with the SuperBase

About this episode

Most runners skip the one phase that actually builds speed. They go straight into marathon-specific training, do the long runs, hit the intervals — and wonder why they plateau after 8 weeks.

The secret? It's called the Super Base. A 4-month training block that builds durability, raises your lactate ceiling, and makes your body ready to handle real speed work without breaking.

In this episode, I break down exactly how it works.

[00:00] – Intro: What is the Super Base?
[01:15] – Why building a base matters (the glass analogy)
[03:00] – Who needs the Super Base?
[04:00] – The 3 key sessions explained
[04:45] – Midweek workout: threshold progression (weeks 1-4)
[06:30] – The V-shaped valley explained (weeks 5-11)
[08:45] – Climbing back up (weeks 12-17)
[10:00] – The endurance spine run (40-50-60 progression)
[11:30] – Hill blasts: why 8 seconds changes everything
[12:30] – How to schedule your week + the 48-hour rule
[13:30] – Why pacing discipline matters
[14:15] – Outro & CTA

  • The glass analogy: Your training capacity is a glass. Base building makes it bigger.

  • Threshold progression: 20 min → 40 min @ threshold in 4 weeks

  • The V-shaped valley: Weeks 5-11 go down in rep length, up in speed. Weeks 12-17 build back up with faster paces.

  • Endurance spine: 30 min warmup + 40/50/60 min @ tempo + 30 min cooldown. Repeat every 3 weeks with faster pace.

  • Hill blasts: 8-second hill sprints to activate glutes and improve stride efficiency

  • The 48-hour rule: Never do a midweek workout and a long run within 48 hours. Protect your key sessions.
