An American man who cycled across 50 countries for charity has been run over and killed by a drunken truck driver in Russia, ITAR-Tass news agency has reported.
Ron McGerity, 61, was killed on a motorway between Kostroma and Ivanovo in central Russia, the agency said.
The driver, whose name was withheld, tried to escape police but was detained.
McGerity arrived in Russia planning to tour all of the Golden Ring on his custom-made Swiss bike.
The Boston native had been on global cycling expeditions to promote peace and raise money for various charities since 1995, detailed on his personal website.
A criminal case has now been opened into the cyclist's death.
