Abraham Kiptum of Kenya set a world record when he ran the Valencia Half Marathon in 58 minutes, 18 seconds Sunday.
"I can't believe it. I'm over the moon," said Kiptum, 29. "Obviously I knew I was in good shape because I set a [personal best] last month in Copenhagen, but I was eager to run in Valencia because it's one of the flattest circuits I've ever run and I was confident of improving on my best."
Kiptum bested the previous record of 58:23 set by Zersenay Tadese of Eritrea in 2010.
Sunday's run was 51 seconds faster than Kiptum's 59:09 in Copenhagen in September.
Gelete Burka won the women's race in 1:06:11.
