Training for Triathlons at an Older Age - NYTimes.comMs. Scott did not have fancy equipment last year when she joined the triathlon training offered by Still Hopes Episcopal Retirement Community in West Columbia. The community’s fitness center trains interested residents and those in the surrounding area who are 55 and older. The program, which had eight participants when it began four years ago, has grown to 20 this year, said Denise Heimlich, the center’s wellness director. They are coached three times a week, for $22.50 a session, by Stefanie Cain, a USA Triathlon certified coach who is the center’s fitness program coordinator.
