Josh Clark is an interaction designer specialising in connected devices, mobile experiences, and responsive design. He is founder of Big Medium, a design agency whose clients include TechCrunch, Time Inc, eBay, O’Reilly Media, and many others.

In a past life, he created the incredibly popular “Couch-to-5K” (C25K) running program, which has helped millions of skeptical would-be exercisers take up jogging. (His motto is the same for fitness as it is for software user experience: no pain, no pain.)
