WOODINVILLE - There was a time when Brian Orton wasn't able to share motorcycle rides with his son Christian. Doctors told him that Christian faced long odds of surviving his fight with kidney disease. ``He had one of the worst conditions,'' said Orton, of Woodinville. ``It was a dire situation.'' But through his father's relentless support and doctors discovering the right combination of medicine, Christian is a healthy and fun-loving 5-year-old who enjoys riding skateboards and joining his father on the motocross track. ``He's doing awesome. I think Christian has been cured,'' Brian Orton said. ``We tried a number of different medications and I also prayed on my knees every night. With the combination of the two, I think we've got our answer.'' While searching for answers, Orton established The NephCure Foundation, a world-wide organization dedicated exclusively to curing glomerular kidney disease. Christian, who was diagnosed with the disease when he was 10 months old, has been in remission for four years. A longtime motorcycle enthusiast, Orton also has established a unique fund-raising event to support his non-profit organization. On Wednesday, he will join 100 other riders in the second annual Seattle 100 at Pacific Raceways in Kent. The endurance race, sponsored by Renton Motorcycles and presented by Orton's company, 2Fast Motorcycle Track Days & Instruction, will run from 9 a.m. to 5 p.m. It is open to the public. Riders and bikes of all descriptions will round the raceway's 10-turn, 2.3-mile road course in timed sessions interrupted by mandatory rest stops. The number of riders is limited in each session to avoid track congestion and promote safety. Participants in the event have raised per-lap pledges and donations, with the proceeds going to The NephCure Foundation. Last year's inaugural event attracted about 15 riders and raised $18,000. But the word spread, and this year's event brought in 100 riders, some of whom are major-league names, with the goal of raising $50,000. Jason Pridmore of American Suzuki, Josh Hayes and Tony Meiring of Attack Kawasaki, and Jake Holden, a Superbike sensation and AMA privateer, are expected to participate. The goal is for each rider to complete 100 laps before 5 p.m. They are encouraged, of course, to complete more, but to do so at moderate speeds. ``This is not a race,'' said Orton, 35, who will drive his Suzuki GSXR 750 in the event and give instruction to riders between lap sessions. ``I'm telling the guys it s not just about the laps. It's about raising funds and doing it safely. We're telling guys to race 80 percent of your ability and not take risks.'' Motorcycles have been a part of Orton's life since he was 7. It's now a family activity with his wife, his son and 3-year-old daughter, Elise. The Seattle 100 was created by Orton out of his love and passion for the sport and his mission to help find a cure for his son's disease. ``We're there for other families,'' he said. ``We're making a difference.'' Orton, who completed 140 laps in last year's event, is looking forward to riding long and strong for his son and others afflicted with the disease. ``You're out there pushing it,'' Orton said of the run. ``It gets pretty tiring after all, but we have a ball. We have a lot of fun.''
