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, which begin at age 40. These calculations are based on Barbara's time of 1:36:09 at age 55. This is not Barbara's best time, which is 1:26:15 at age 40, but it is the best age corrected. Barbara's four races between ages 52 and 55 were remarkable---essentially on her line each race. Her races at ages 61 and 62 were also essentially on her line. Barbara is one of my best examples of people staying on their line. See in particular the discussion of her 5K times on this site.
