Brick Sessions for Runners

By Alice Tim, Certified Running Coach · September 10, 2025 · 9 min read

There is a lot of noise online about brick sessions. This page strips it back to what actually moves the needle for everyday runners.

Timing is everything. Slot brick sessions into your week around your hardest run so the two support rather than sabotage each other. Recovery is where the adaptation happens. The work of brick sessions breaks you down; the hours afterward are what actually make you stronger.

Why Brick Sessions Matters

Keep a simple log. Writing down how brick sessions felt turns vague impressions into data you can use to adjust before small problems become big ones. Cross-training buys you aerobic fitness on days your legs need a break from impact. It is maintenance, not cheating.

Getting Started: The Basics

The good news about brick sessions is that you do not need anything fancy to begin. Start here:

  1. Begin at a level that feels almost too easy; you can always add more next month.
  2. Give it four weeks before judging results; adaptation is patient work.
  3. Track one simple metric so you can see progress without obsessing over data.
  4. Pair the new habit with an existing one, like your easy run, to make it stick.

Common Mistakes to Avoid

  • Skipping the warm-up because the watch is already running.
  • Doing too much too soon and mistaking soreness for progress.
  • Chasing numbers on a screen instead of how the effort actually feels.
  • Ignoring niggles until they become full-blown injuries.

How to Measure Progress

  • Track how brick sessions feels on a simple one-to-ten scale after each session.
  • Note your resting heart rate trend; a creeping rise often flags under-recovery before aches appear.
  • Re-test a short benchmark every four weeks so improvement becomes visible, not imagined.

Key Takeaways

  • Brick Sessions rewards consistency far more than intensity.
  • Start easy, progress slowly, and log how it feels.
  • Slot it around your hardest run so the two support each other.
  • Avoid the common mistakes above and you will stay healthy.
