This one-on-one finds us on a birthday, so Nikki and Chad chat about not feeling your age and what factors contribute to being 49 but feeling 29. They also talk about the Six Gap Century event, the running explosion, Strava’s newly released data, why group runs are more inviting than group rides, what employers can do to capitalize on running’s popularity, and how Nikki runs in the wilderness with nothing but bear spray and Ronnie Milsap to keep her company. They also give a special shout-out to Children’s Healthcare of Atlanta, who successfully moved into their new Arthur M. Blank Hospital over the weekend.
