German cyclist Tony Martin won four time trial world championships over the course of his 14-year professional career, but only one Olympic medal.
Now he's parting with it, with hopes that it will help those in need.
Martin announced Sunday that he is auctioning off the silver medal he won at the 2012 Summer Olympics in London to raise money for Ukrainian children and their families through RTL – Wir helfen Kindern, a German charity organization.
As of Monday night, the leading bid had already eclipsed 12,000 euros – more than $13,300. The auction runs through April 9.
