In the 2010 outdoor season Spiegelburg started with a win at the Qatar Athletic Super Grand Prix – the first stop on the inaugural 2010 IAAF Diamond League. She was narrowly defeated by Svetlana Feofanova at the 2010 European Team Championships, but then beat Lisa Ryzih to claim another national title at the German Championships. She was behind Feofanova at the 2010 European Athletics Championships, but was also ahead of Ryzih, and she left the competition with a European silver medal. She also improved her outdoor best to 4.71 m that season.
