Running up to 140 miles each week isn’t something most lawyers have the time, or desire, to pursue. Adam Campbell explains why he quit his comfortable job as an attorney for the discomfort of professionally running ultramarathons – races longer than marathons that can be over 100 miles long. Campbell shares the intense physical and emotional effects from running such distances – all captured in Silence, the film about his passion for the sport.
