The Clay Walker Band Against MS bike ride took place in Humble.
600 riders turned out for the event.
It raises money for research to find a cure for MS.
Country music star Clay Walker has battled MS since 1996. He's been a spokesperson for the organization.
"I've got both a cousin and a family friend who are struggling with MS and I wanted to my part and family and I decided at the first of the year that every month we're going to do something charity wise, just try to give back every month," said Kevin Miles, a participant.
Over the past 14 years, Band Against MS has raised $4 million.
