Organizers have cancelled the first day of the BP MS 150 bike ride.

They blamed the cancellation on conditions at the overnight site in La Grange and expected severe weather in the area.

“Excessive rainfall and wind that occurred throughout this week has had a significant impact on the two sites where a majority of teams and cyclists camp overnight, Fayette County Fairgrounds and Camp St. Mark’s, and have been determined unsafe and inaccessible,” according to an announcement sent to participants in the two-day fund-raising ride, which starts in Houston and finishes in Austin. “The City of La Grange Office of Emergency Management has closed these sites.”

Bicyclists are asked not to ride the route on Saturday.

“The route on Day 1 will be closed and all standard support services – rider support, transportation and breakpoints – along the route will be suspended on Saturday,” the announcement said. “The safety and security of all participants are our top priorities, but ultimately your safety is your personal responsibility.”

As of 1 p.m. Friday, the second day of the ride, from La Grange to Austin, was still set to go on schedule. The ride will start at 8 a.m. at the Fayette County Courthouse in La Grange, 151 N. Washington Street.

“We are currently assessing the logistics and route conditions from La Grange to Austin and will continue to provide updates here and the BP MS 150 Facebook Page as details become available,” officials said.
