Race Pace Calculator

Convert running pace, time, and distance into projected 5K, 10K, half marathon, and marathon finish times.

Interpreting results

Use the numbers with the right level of caution

These tools split into three different jobs: modelling exported Garmin activity data, reading context for BMI and blood pressure, and pace planning for running events.

BMI and blood pressure pages are not diagnostic tools. They help you understand the category a reading falls into and prepare figures that may be requested elsewhere.

Understanding training data

Use Garmin Data Analysis & Modelling when you want to move beyond pace charts and ask which available activity, sleep, heart-rate or load factors are associated with performance.

Garmin DataRace Pace

Preparing a health report

Use BMI when a form asks for height and weight context, and Blood Pressure Range to understand where a reading sits before checking appropriate clinical guidance.

NHS BMIBlood Pressure

Planning a race target

Use Race Pace for single-discipline running targets and quick finish-time comparisons.

Important context

Some health numbers need interpretation, not overconfidence

  • Garmin Data Analysis & Modelling focuses on models: filter activities, inspect trends and compare holdout validation.
  • BMI uses adult threshold bands while clearly showing why BMI can be a blunt measure.
  • Blood Pressure places systolic and diastolic readings on one combined range chart.
  • Race Pace is a planning tool for even pace, race projections and finish-time targets, not a physiology forecast.

FAQs

Health and Fitness Tool Questions

Does Garmin Data Analysis & Modelling store my archive?

The browser sends the zip archive to a TallyKind API route, which forwards it to the separate analyser service for the request. Uploaded archives are intended to be temporary; use the example archive mode if you want to test the utility without uploading your own data.

Are TallyKind health calculators medical advice?

No. They are informational tools for understanding readings or planning pace. They do not diagnose conditions or replace NHS or clinician guidance.

Why is BMI treated carefully?

BMI can be misleading because it does not directly measure body fat, muscle mass, fitness or fat distribution. It is best treated as a screening/reporting number.

Why might race pace projections miss my actual result?

They use even-pace maths. Course profile, weather, fatigue, training, fuelling, transitions, equipment and race conditions can materially change actual performance.
