05 · Perform on the day

Turn training into race-day decisions

Rehearse pacing, fueling, equipment, transitions, cutoffs, and taper decisions before the event asks you to make them under pressure.

The direct answer

What to do at this stage

Race-day execution should feel rehearsed, not improvised. Turn training into a small set of decisions you have already practised: opening pace, fueling rhythm, equipment, transitions, course constraints, and what you will do when the day stops matching the ideal plan.

Ask before acting

Three decisions to make honestly

  1. 1

    What pace or effort can I defend after the excitement fades?

  2. 2

    What must be practised in training before it belongs in the race plan?

  3. 3

    Which course, cutoff, weather, or transition constraints can change the plan?

A practical sequence

What to do next

  1. Step 1

    Define conservative anchors

    Choose effort, pace, fueling, and timing ranges that leave room for course and condition changes.

  2. Step 2

    Rehearse the system

    Practise equipment, nutrition, transitions, and decision points during suitable training sessions.

  3. Step 3

    Taper without testing

    Reduce fatigue while keeping familiar movement; the final week is not a chance to prove fitness.

  4. Step 4

    Write the fallback

    Decide in advance how you will respond to early pace errors, missed fuel, weather, or a difficult patch.

Avoid the trap

Common mistakes at this stage

  • Opening at an effort supported by adrenaline rather than training evidence.
  • Trying new fueling, footwear, or equipment on race day.
  • Building a plan that works only if every split and condition is perfect.
