Setting a new personal best is always nice but setting personal bests for two distances in the same race is special. This past weekend at the Rock ‘n Roll Las Vegas Half Marathon Run SMART client Ilea Eskildsen managed to set a new 10k PR during her half marathon. When she signed up for private coaching with Dr. Jack Daniels her 10k PR was 40:33. In Sunday’s race she came through 10k in 36:53, almost four minutes faster than she used to run for 10k alone! This set her up for a very impressive new half marathon PR of 1:21:04 (full results). Her previous half marathon PR was 1:23:53 set this past June.
