Jeff and I started running in earnest in 2012, starting with our first 5K together in September. After that first one, we ran several more together including a 5k Turkey Trot with my family Thanksgiving of 2012, a 10k in December of 2012, and the ever-fun Color Run 5K in February of 2013. In March of 2013, Jeff even ran the LA Marathon! Running has been a great way for Jeff and I to bond, and exercise, and it has become a passion of both of ours, supporting each other through races, injuries, styles of running, and catching us both up on the world of RadioLab, or books on tape.
