Eiko makes CNN!

Amidst the sea of jerseys and bike shorts at New Jersey's City to Shore -- a 150-mile bike ride to benefit multiple sclerosis research -- one unlikely rider stands out.

A tiny 84-year-old woman wears a neat, green turtleneck dress and an embroidered jacket. On her feet is a pair of high-heeled pumps. Her salt-and-pepper hair peeks out from the helmet that indicates she is, in fact, a participant in the bike ride. Her old-fashioned one-speed bicycle is purple, with a large wire basket on the front that carries her belongings and her number for the ride.

Lan Yin Tsai doesn't give the impression that she could go five miles on that bike, let alone 150. But that's what she's done -- for the past 26 years. Eiko, as she's known to friends and family, is an institution at the annual City to Shore event. And over the years, she has become a symbol of hope and determination for City to Shore participants and MS patients.

Now that's what I call a lady!!
