The predicted minimum times were computed on the aging part of this site: Aging in Sports and Chess. The new, 2018 age factors have been used. These calculations are based on John's time of 1:26:02 at age 61. This is not John's personal best time, which is 1:19:33 at age 52, but it is his best age corrected time. John's six best age corrected times (all less that 2 minutes off his line) are at ages 52, 60, 61, 62, 66, and 67.
