The predicted minimum times were computed using the page: Compute Aging Effects. The new, 2018 age factors have been used. Even though my best time ever was 2:58:45 at age 45, my best age corrected time according to the age factors was 3:10:00 at age 53. My four best age corrected times (all less than 4 minutes off my line) are at ages 45, 47, 53, and 53.
