Registration is open for the Charleston Sprint Triathlon Series.

The competition at James Island County Park kicks off May 20 and continues June 17, July 8 and July 29, with the Championship Race set for Aug. 12.

The swim-bike-run, now in its 22nd year, recently was named one of the Top Ten Charleston Signature Sport Events by the Charleston Metro Sports Council, placing it in good company with other Charleston favorites, including the Family Circle Tennis Cup and the Cooper River Bridge Run.

Each competition begins at 7:15 a.m. with a 600-yard freshwater swim in the lake at James Island County Park, continues with a 12-mile bike ride and finishes with a flat 5K run.

Athletes may sign up for all the series races or just one.

A discounted registration fee is offered for registration for three, four or five races. Series registration must be made by May 20. Each race is limited to 375 participants, and fees start at $55 per race.

Awards will be presented to the top five men and the top three women finishers in the Open/Elite division.

Awards also will be presented to the top three age group winners in five-year increments, as well as to the top male and female finishers over the age of 40 (Masters division).

Participants may choose to compete in the Clydesdale (men over 200 pounds), Athena (women over 150 pounds) or Masters Clydesdales (men over age 40 and over 200 pounds) divisions. Awards will be presented to the top three competitors in each of those divisions.
