在线免费跑步配速计算器

Pace = Time ÷ Distance. For a 5K (3.1 miles) in 25 minutes: 25 ÷ 5 = 5:00 min/km or 25 ÷ 3.1 = 8:04 min/mile. The calculator computes this instantly from any two values.

Multiply min/km by 1.60934. So 5:00 min/km = 5 × 1.609 = 8:03 min/mile. The tool shows both units simultaneously after calculation.

Average recreational runner: 10–12 min/mile (6–7:30 min/km). Solid amateur: 8–9 min/mile (5–5:36 min/km). Good club runner: 6–7 min/mile (3:44–4:21 min/km). Elite/competitive: under 5 min/mile (3:06 min/km).

Use the race predictor tab. A common formula: Marathon time ≈ 5K time × 9.27. This is approximate — marathon pace is significantly slower than 5K pace due to endurance demands. The predictor uses the Riegel formula for more accuracy.

A negative split means running the second half of a race faster than the first. It's the most efficient race strategy — starting slightly slower than goal pace prevents early fatigue. Set your first-half goal pace 5–10 seconds/km slower than average target.

Yes, the 跑步配速计算器 on Allio Tools is completely free with no sign-up or registration required. It works directly in your browser.

计算您的跑步配速、速度和预计完赛时间。 No data is sent to a server — everything runs locally in your browser for maximum privacy and speed.

No installation needed. The 跑步配速计算器 runs entirely in your web browser on any device — desktop, tablet, or mobile.

Completely safe. The 跑步配速计算器 processes everything locally in your browser. No input data, results, or usage information is ever transmitted to or stored on any server.

After the page loads for the first time, the 跑步配速计算器 works without an internet connection for all client-side processing. Tools that fetch live external data (such as DNS or network lookups) require an active connection.

The 跑步配速计算器 uses clinically validated formulas such as the Mifflin–St Jeor or Harris–Benedict equations where applicable. Results are population-based estimates and can differ from measured values by 10–20% for individuals with atypical body composition. See our <a href="/methodology/">Methodology page</a> for full formula sources and references. Consult a qualified healthcare professional before making medical or dietary decisions.

The 跑步配速计算器 uses an established, peer-reviewed formula endorsed by leading health organisations such as the WHO, CDC, or NIH where applicable. The specific formula is chosen for its validated accuracy across diverse adult populations under normal conditions.

Yes. The 跑步配速计算器 is built with standard browser APIs and works on all modern browsers including Chrome, Firefox, Safari, and Edge — on both desktop and mobile. No plugins, extensions, or third-party software are required.
