Britain's Jodie Stimpson wins 2nd straight world series triathlon in Cape Town

CAPE TOWN, South Africa - Jodie Stimpson won her second straight world series triathlon when she outlasted British teammate Helen Jenkins in a running duel Saturday.

Stimpson was in a group of 12 competitors that broke away during the bike leg and began the run with more than two minutes on the chasers.

Stimpson hit the front and looked set to cruise to victory as she did in the series opener in Auckland this month, but Jenkins caught her midway through the 10-kilometre run and the lead changed constantly. Only in the last 500 metres did Stimpson finally break from Jenkins, and won her third career world series title by seven seconds.

American Gwen Jorgensen, part of the chasing group two minutes down, stormed to third, 22 seconds behind.

Victoria's Kirsten Sweetland was seventh in one hour 48 minutes five seconds while Winnipeg's Sarah-Anne Brault was 19thin 1:49:27.

"I made some good decisions," said Sweetland. "I was a little overzealous on the bike and got a little excited.

"I think I paid for it on the run, but you know I was in the mix for my best ever WTS finish and I'm pleased."
