Threshold and tempo training

Training at and around threshold — determining threshold intensity, tempo and cruise intervals, and their place in hybrid programmes.

Learning objectives

  • Identify threshold intensity using field methods
  • Design tempo and cruise interval sessions
  • Progress threshold training
  • Place threshold work within a weekly plan

Before this lesson

Why this matters

Fitness races are mostly run near threshold. Raising threshold raises race pace.

Defining threshold

Threshold lies near the boundary between heavy and severe domains (critical power/maximal lactate steady state) [poole2016]. Methods differ, so treat any value as an estimate [jamnick2020].

Field methods

  • 30-min time trial: average pace/HR ≈ threshold
  • RPE 6–7/10; can speak short phrases

Sessions

SessionExample
Tempo run20–30 min continuous
Cruise intervals4–5 × 6–8 min, 1–2 min easy
Threshold bike/row3 × 10 min

Progress by adding time at threshold (e.g., 20 → 40 min). Keep most training easy [seiler2010].

Common mistakes and misconceptions

Case study

An athlete’s 30-min time trial gives a threshold pace of 4:50/km. He progresses cruise intervals from 3 × 8 to 5 × 8 min over six weeks; his race pace improves by 10 s/km.

Answer B. Comfortably hard.

2. A field estimate of threshold is…

Answer B. Time-trial method.

5. In fitness races, threshold pace matters because…

Answer B. Sustained effort.

Short-answer & application questions

  1. Estimate threshold pace from a recent 5 km.
  2. Design a 6-week threshold progression.
  3. Explain “comfortably hard” to a client.

Key takeaways

  • Threshold work targets the heavy domain, near the maximal sustainable steady state.
  • Field estimates: ~30-minute time-trial pace/HR, RPE 6–7, “comfortably hard”.
  • Cruise intervals (e.g., 4 × 8 min, 1–2 min rest) accumulate time at threshold.
  • Threshold pace is highly relevant to fitness races.
