New Course, New Record Set for Live Semper 5ive Event

Hosted in new location aboard Marine Corps Base Quantico


QUANTICO, VA (May 18, 2021) – More than 300 runners from 18 states attended the live Semper 5ive on Saturday, May 15 aboard Marine Corps Base Quantico. An additional 4,446 runners across the United States and 22 countries completed the virtual Semper 5ive, as well as the sold out Marine Corps Historic Half and Devil Dog Double events between April 24 and May 16.


Jonathan Ladson, 29, from Dale City, VA crossed the finish line first with a time of 26:03, setting a new course record for the Semper 5ive event. “My goal was to redeem myself from the 17.75K in March and then when I heard that the course record was 27:18, that became my secondary goal.”

Rounding out the top male finishers are Samuel Yakulis, 17 from Stafford, VA with 27:30 and Montano Klingsporn, 22, from Clarksville, VA with 27:49, placing second and third respectively.

Leading the female finishers was Sarah Scully, 25, from Arlington, VA with a time of 33:14. Catherine Miller, 54, from Spotsylvania, VA earned second place for women in 33:52, followed closely by Elizabeth Kukla, 27, from Richmond, VA in third place with a time of 34:55.

Additional event highlights include:

  • The youngest runner, Alyssa Deleon, 10, from King George, VA secured the award for the female 7-10 age division with a time of 1:14:05, while the oldest runner Jewell Martin-Grigsby, 89, from Stafford, VA finished in 1:22:41, also earning the age award for the female 70 & Over division.  
  • Three runners, including Caitlin Hodge, 27, from Washington, PA (58;51), Garett Covert, 12, from Fredericksburg, VA (55:52) and Joshua Summits, 39, from Stafford, VA (37:20) celebrated their birthday on event day
  • Textron Systems was on site to display the new CottonmouthTM Advanced Reconnaissance Vehicle —a next-generation amphibious scout vehicle.
