Sarah and Dimity welcome a bevy of guests as they record in front of a live audience at a lululemon store in Kansas City just days before the Kansas City Marathon. After extolling why they are so pleased to return to the place where they launched their second book, Train Like a Mother, the duo kicks things off with Kim Fassetta from AfterShokz. This mother runner and marketing whiz talks about round 2 of marathon training after opting out of her debut 26.2 the day before the race—in Greece! Next, father runner Joe “Mr. Garmin” Heikes joins the conversation along with Jenni Prado, a mom of three who is running her second half-marathon on Saturday. Like Jenni, Joe sees the wisdom in keeping it simple and tracking workouts online. Next is empty-nester Catherine Brown, who’s using the Kansas City Half-Marathon as a training run for the Disney Dopey Challenge. A convert to heart-rate training, Catherine admits to having to check her ego at the door when she made the switch. Joe explains the differences measuring heart rate at the wrist versus the chest; for all runners, Mr. Garmin suggests two critical-yet-underutilized GPS watch functions. The final guest is mom of two Katie Hearn, whose tenth half-marathon this weekend will be her second post-baby—and she admits she’s aiming to better her pre-baby 13.1 PR! During a segment when Dimity and Sarah pepper Joe with questions based on their personal GPS experiences, Joe talks about why it’s more important to check data on some training days than others and how to best use a Garmin during a race. (SBS is now fired up to run a race just to utilize to the “set-a-target” feature!) Toward the end of the show, Joe answers the burning question all GPS-wearing runners wonder.
