Running Pace: 5 Mistakes to Avoid

Updated 5 Oct 2026 in Health & Fitness

Calculates pace for runs like the Standard Chartered Marathon or IPPT 2.4 km. The maths is not complicated, but a handful of errors come up again and again in this and related health & fitness calculations. Here is what to watch for.

Research has shown that Asians tend to develop conditions such as type 2 diabetes and heart disease at lower body weights than Europeans. That is why the Health Promotion Board recommends lower BMI cut-offs for Singaporeans, with 23 marking the start of moderate risk.

Energy needs depend on age, sex, size and activity. Formulas such as Mifflin-St Jeor estimate resting needs, and an activity multiplier turns that into daily needs. Real requirements vary by a few hundred calories, so adjust based on how your weight changes over several weeks.

1. Using international BMI cut-offs for Asians

HPB recommends lower cut-offs because risks rise at lower BMIs in Asian populations.

2. Treating estimates as exact

Formulas such as BMR or body fat are population estimates with real margins of error.

3. Measuring inconsistently

Tape measurements change with posture and breathing; measure the same way each time.

4. Cutting calories too aggressively

Very large deficits are hard to sustain and can lead to muscle loss.

5. Relying on a single measurement

Weight and heart rate fluctuate daily; trends tell you more.

The correct method

Pace = time ÷ distance.
