At 9 a.m. Saturday, the Parris Island Triathlon will kick off the 2014 S.C. Triathlon Series.
Almost 400 participants from 13 states will start at the Parris Island Military Combat Training Pool with a 500-meter swim, bike 10 miles on a flat and fast track and finish with a 3.1-mile run.
Of the 397 racers registered through Thursday night, 28 are older than 60, including 83-year-old Paul Webster of Lancaster, running in his 10th SCTS season.
"I find it a challenge and something to do to keep in shape," Webster said in a release. "So far my health has allowed such activity."
York's Ken Correll, 63, will be competing in his 101st triathlon. He hit the 100 mark in last year's season-ending Hilton Head Triathlon.
It doesn't look like there will be any repeat champions Saturday morning.
As of Thursday, two-time defending women's champion Kelli King of Bluffton (56:40 in 2014) and 2014 men's champion Ian Blake of Charleston (51:29) were not registered.
