比賽成績預測器
一次真實的比賽或計時跑就能預測你在其他距離上的成績。輸入你跑過的距離和所花時間，本預測器就會使用著名的里格爾公式估算你的 1500m、5K、10K、10英里、半程馬拉松和馬拉松成績，以及每個項目的每公里配速。預測結果假設條件相似，且你已為更長的項目進行適當訓練，可協助你設定切合實際的比賽目標與配速。
使用里格爾（Riegel）公式（T2 = T1 × (D2/D1)^1.06）。預測結果假設條件相似，並已針對更長距離進行適當的耐力訓練；若缺乏足夠的長距離跑準備，實際馬拉松成績通常會比預測的慢。
常見問題
- 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.
