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.

Tagahula ng Oras ng Karera

Ang isang tapat na karera o pagsubok laban sa oras ay maaaring humula ng iyong oras sa ibang mga distansya. Ilagay ang distansyang tinakbo mo at ang oras na inabot nito, at ginagamit ng tagahulang ito ang kilalang pormula ng Riegel upang tantiyahin ang iyong oras sa 1500 m, 5K, 10K, 10 milya, kalahating maraton at maraton, kasama ang bilis kada kilometro para sa bawat isa. Ipinagpapalagay ng mga hula ang magkatulad na kondisyon at na nagsasanay ka nang naaangkop para sa mas mahahabang takbo — nagtatakda ang mga ito ng makatotohanang layunin sa karera at tamang bilis.

Gumagamit ng pormula ng Riegel (T2 = T1 × (D2/D1)^1.06). Ipinagpapalagay ng mga hula ang magkatulad na kondisyon at angkop na pagsasanay sa tibay para sa mas mahabang distansya; kung walang sapat na paghahanda sa mahabang takbo, ang totoong oras sa maraton ay kadalasang mas mabagal kaysa sa hinulaan.
