The Valencia themepark is shutting down Colossus on August 16.
To celebrate the end of an era for the 36-year-old ride, the park invited two dozen people to ride the roller coaster for 36 straight hours starting 9 a.m. Monday.
Michael Mountain, 15, of Bakersfield was among the two dozen people to accept the challenge.
Mountain was one of six people to complete the entire Colossus marathon Tuesday night.
Mountain shared his experience on 17 News at Sunrise Wednesday morning.
"It was fun for about the first 20 hours. But then as soon as it got to 40 degrees, which nobody was prepared for, we were frost bitten, hallucinating. I thought the moon was a disco ball."
The participants received annual VIP park passes to Magic Mountain, and also took home a piece of the historic roller coaster.
Six Flags will announce the ride's replacement August 28.
