The predicted minimum times were computed on the aging part of this site: Aging in Sports and Chess. These calculations are based on an age corrected best time of 21:38 at age 58. This is not Barbara's best time, which is 20:11 at age 42 but it is the best age corrected. If one counts as being on the line any difference less than or equal to 0:52, then Barbara has been on her line for all but 3 of her last 13 races---since age 50. The 2016 race was her second best race of the 23 races age corrected, off by only 8 seconds!
