What is a race time predictor?

A race time predictor estimates your finish times at other distances from one recent race result. By entering a known time, you can forecast your likely 5K, 10K, half-marathon and marathon performances to help set realistic pacing and goals.

How accurate is the Riegel race prediction formula?

Riegel's formula scales time with distance using an endurance exponent of about 1.06. It is most accurate for distances close to your input race and for well-trained runners; predictions for much longer events assume adequate endurance training.

Why is my predicted marathon time slower than expected?

Longer races expose endurance and fueling limits that short races do not, so the formula intentionally adds time as distance grows. If your marathon training is strong you may beat the estimate; if undertrained, you may fall short.

Peramal Masa Perlumbaan

Satu perlumbaan jujur atau ujian masa boleh meramal masa anda pada jarak lain. Masukkan jarak yang anda larikan dan masa yang diambil, dan peramal ini menggunakan formula Riegel yang terkenal untuk menganggar masa anda pada 1500 m, 5K, 10K, 10 batu, separuh maraton dan maraton, lengkap dengan rentak per kilometer untuk setiap satu. Ramalan menganggap keadaan yang serupa dan anda berlatih dengan sewajarnya untuk acara yang lebih panjang — ia menetapkan sasaran perlumbaan yang realistik dan rentak yang sesuai.

Menggunakan formula Riegel (T2 = T1 × (D2/D1)^1.06). Ramalan menganggap keadaan yang serupa dan latihan ketahanan yang sesuai untuk jarak yang lebih jauh; tanpa persediaan larian jauh yang mencukupi, masa maraton sebenar biasanya lebih perlahan daripada yang diramalkan.
