比赛成绩预测器
一次真实的比赛或计时跑就能预测你在其他距离上的成绩。输入你跑过的距离和所用时间，本预测器就会使用著名的里格尔公式估算你的 1500m、5K、10K、10英里、半程马拉松和马拉松成绩，以及每个项目的每公里配速。预测结果假设条件相似，且你已为更长的项目进行适当训练，可帮助你设定切合实际的比赛目标与配速。
使用里格尔（Riegel）公式（T2 = T1 × (D2/D1)^1.06）。预测结果假设条件相似，并已针对更长距离进行适当的耐力训练；如果缺少足够的长距离跑准备，实际马拉松成绩通常会比预测的慢。
常见问题
- 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.
