How can the visually-impaired go out and exercise more? This simple question drove  Chatchai Aphibanpoonpon, 31, of toy company Klong Don Sor, to start a program pairing abled and visually-impaired runners. Run Together, on Mar 20, will be the biggest such run yet, with 360 blind runners expected. We spoke to Chatchai, and running partners Piriya Veeramanomai, 27, Suwit Intaranukulkit, 28, Nattaya Pariwat, 30, Sutham Pongsampao, 20, about what motivates them to run together.
