In January 2010, Ennis captained the GB & NI team that won the Aviva International Match at Kelvin Hall in Glasgow.
Ennis caused a surprise in winning the 60 metres hurdles in a British record time of 7.95 seconds, two hundredths of a second ahead of world indoor champion Lolo Jones.

Afterwards Jones, who hadn't lost in over two years in her event, expressed shock at being beaten by a multi-eventer, saying; "I'm looking forward to not letting heptathletes beat me when I'm only working on one thing.
That's kind of crazy."

At the same meeting Ennis set a new indoor personal best in the high jump of 1.94 metres.

At the World Indoor Championships in Doha, Qatar, Ennis became the World Indoor Champion for the pentathlon with a new British, Commonwealth and Championship Record score of 4,937 points, finishing ahead of all three Beijing heptathlon medal winners, Nataliya Dobrynska, Hyleas Fountain and Tatyana Chernova.
As a consequence Ennis became the first British woman to win world titles both indoors and outdoors.
