Half Marathon Training: Focused on Mind; Kristy is doing a half marathon in 40 days and has not fully started to train; treating it as an experience; Kristy uses goals to help motivate while Amanda just makes it part of her day; interesting how folks are motivated differently; walking as a great way to stay active every day; what it takes to get to 10,000 steps a day; endorsed by Valter Longo as well.
