  1. The table shows differences between predicted and observed race times. A negative time indicates that predicted race time is shorter than observed, that is, predicted velocity is too fast. The table shows that, for instance, nearly 25 % of runners have a predicted race time from the Riegel formula greater than 20 min too fast
