Endurance athlete Vi Jones-Medusky and artist Peggy Chun hope to raise awareness about the paralyzing ailment both are fighting — Amyotrophic Lateral Sclerosis, or Lou Gehrig's disease — through a four-mile run-walk Oct. 18 through Kualoa Ranch.

Participants will make their way around a looping course along jeep roads and cow pastures through the lush valley. There will be a fresh water stream crossing and single-track trail to the finish with scenic ocean views. It is limited to 280 participants of all ages and abilities.

The deadline for registration and the $18 fee is Sept. 18. Participants will receive a T-shirt emblazoned with an original Peggy Chun artwork.

For more information, call the Muscular Dystrophy Association ALS Division at 593-4454.

Jones-Medusky finished several marathons, Ironman triathlons and ultra marathons before she was diagnosed in 2004. She hopes to use a wheelchair to navigate the course.

Chun, a well-known Hawaii watercolorist, was diagnosed in 2002. Chun is now bedridden and 100 percent dependent on a ventilator, so she will not attend.
