CERRITOS, Calif.—Doug Shull, a quadriplegic from Morton, Ill., and his lifelong friend Chris Ackerman took part in the Honda LA Marathon on March 20 with the help of a wheelchair donated by ATG Rehab. Quantum Rehab manufactured the specially outfitted Litestream XF ultra light manual wheelchair. Shull, 54, and Ackerman, 53, who graduated from high school together, competed in the marathon 25 years ago and decided to do it again to raise money for World Vision, a children’s charity. Ackerman pushed Shull in the 26-mile event, held March 20. The two finished the marathon in 4 hours and 47 minutes.
