About 200 cyclists participating in the Ride the Rockies tour needed a lift on Berthoud Pass on Sunday because of blizzardlike conditions caused by the upper-level cold that swept in from the northwest Sunday afternoon.
The same system spawned thunderstorms, hail, lightning and at least one tornado in the eastern Denver metro area and a rare mountain tornado reported in Park County.
Riders reported hypothermialike symptoms and some minor injuries from falls caused by the snow-slick roads, said Nowell Curran, a deputy chief with Grand County EMS.
Agencies in the area were marshaling vehicles to transport the riders about 15 miles to the Grand Park Community Recreation Center in Fraser.
"Basically, we're just trying to get some cold people down to a warm building," Curran said.
The six-day ride began Sunday morning in Boulder with about 2,000 riders who were slated to cover 89 miles on the first day, eventually crossing 471 miles and six mountain passes.
