Armstrong has been in northwest Iowa for RAGBRAI before. In 2007 he dipped his bike tire in the Rock River in Rock Rapids. That was years before the international athlete was stripped of his Tour de France titles, in August of 2012 after a doping scandal.
This time, according to RAGBRAI, Armstrong plans to be a guest bartender at a Rock Valley street party to raise money for the town that was among those struck by flooding last month.
Armstrong says RAGBRAI was the first organization to support and welcome him back after he was stripped of his titles, and he will always remember that.
