Yorba Linda Boy, 8, To Climb Mount Kilimanjaro For 'CureDuchenne'

STUDIO CITY (CBS) — At just 7 years old, Yorba Linda native Tyler Armstrong became the youngest climber to ever summit Mount Whitney in a single day. Tyler and his father, Kevin Armstrong, climbed the highest peak in the United States last year to raise money for CureDuchenne, a nonprofit organization dedicated to funding research for Duchenne muscular dystrophy.

Tyler, now 8, is challenging himself once again and stopped by KCAL9 to discuss his next adventure. This time, his goal is to become the second youngest person ever to summit Mount Kilimanjaro. While Tyler takes on the mighty climb, he challenges others to donate a dollar to CureDuchenne for every foot he climbs.

"I'm climbing 19,341 feet to the top of Mt. Kilimanjaro for boys with Duchenne who can't," Armstrong says. "If people donate one dollar for every foot I climb, we can raise a lot of money to help find a cure for Duchenne."

As the most common and lethal form of muscular dystrophy, Duchenne impacts on one in 3,500 boys.
