Lance Armstrong says an early investment in Uber has “saved” his family after paying out $111m (£86.8m) in legal fees and settlements.
The American, 47, was stripped of his seven Tour de France titles and banned from cycling for life in 2012 beforeadmitting to using performance-enhancing drugs.
He says he gave $100,000 (£78,212) to a venture capital fund that invested in the ride-hailing app in 2010.
“It’s saved our family,” he told CNBC.
In April, Armstrong agreed to pay $5m (£3.9m) to the US government to settle a long-running lawsuit that could have cost him $100m (£78m) in damages.
However, he said he felt he did not “get off scot free” as other settlements and legal fees meant he had to pay $111m in total.
Armstrong, who has five children, did not say how much he had earned from his Uber investment but added it was “too good to be true”.
