Pacing for Long COVID: Recognizing Your Exertion Limits

Not all Long COVID fatigue is the same — but anyone experiencing PEM should understand pacing before the next activity increase turns into a setback.

Long COVID (also called post-COVID condition or PASC) describes persistent symptoms after a COVID-19 infection. A subset of those affected develop a symptom picture that closely resembles ME/CFS — including post-exertional malaise (PEM): a delayed worsening after exertion, often 12 to 72 hours later. For this subgroup, pacing is the most important non-drug strategy for avoiding setbacks.

Why "just move more" can be risky

Many people with Long COVID are initially given the well-meaning advice to gradually increase their activity. For the subgroup with PEM, however, this can lead to repeated crashes and a gradual decline. US and UK health authorities (CDC, NICE) now recommend checking first whether PEM is present — and if so, starting with pacing rather than activity progression.

First steps for pacing with Long COVID

  • Recognize PEM. Does the worsening occur with a delay (hours to days) after exertion? That's a hallmark feature pointing toward pacing rather than graded activation.
  • Keep a symptom diary. Symptoms in Long COVID often fluctuate a lot — a diary reveals patterns that stay invisible in the moment.
  • Consider accompanying symptoms. A racing heart on standing, dizziness or lightheadedness can point to accompanying orthostatic intolerance (e.g. POTS) — common in Long COVID.
  • Start realistically, not ambitiously. Baseline after an infection is often well below what was possible before — that's not a sign of regression, it's the real starting point.

How mypacing helps with Long COVID

Open the pacing calculator — guidance on your daily exertion limit Start the stand test — for a racing heart or dizziness when standing up

The pacing calculator is instant and free. The guided stand test (NASA lean test) generates a structured finding for your doctor's visit. The app's daily tracking view links wearable data (Garmin, Apple Health, Whoop, Oura and more) with symptom entries — or works entirely without a device, using manual entries alone.

Note: mypacing is not a medical device and does not replace medical diagnosis or treatment.
