""The father-and-son team began running races in 1977, competing in more than 1,000 marathons, #duathlons and #triathlons," In a custom racing chair, Rick -- who had cerebral palsy that left him a quadriplegic -- told his father that running in the race made him feel like his disability disappeared."
