Denver man completes World Marathon Challenge to honor father with Parkinson’s disease

DENVER (KDVR) — A Denver man recently completed seven marathons in seven days on seven different continents, all in honor of his father who is diagnosed with Parkinson’s disease.

Karan Rai is one of about 200 people to complete the World Marathon Challenge, raising more than $80,000 for the Parkinson’s Foundation through their Parkinson’s Champions program. 

“This was so far out of my comfort zone I just had to do it,” Rai said. 

His father, Ranjit, who lives with the neurodegenerative disease associated with a progressive loss of motor control, was the inspiration behind it all. Ranjit was a veteran of the Indian Armed Forces and served at the highest levels in the special operations community for nearly 23 years.
