Registration is open for the annual Crystal City Twilighter 5K.

The Pacers-organized race is scheduled to take place at 8:30 p.m. on Saturday, July 21. The start and finish will be located on Crystal Drive between 20th and 23rd Streets. Cash prizes will be awarded to the top 5 overall male and female finishers. Merchandise prizes will be awarded to the top three male and female finishers in 10 different age groups, from 0-5 to 70+.

Unlike in previous years, the race course is now expected to take runners mostly south instead of north. Due to construction on the northern end of Crystal Drive, we’re told that runners will now head south on Potomac Avenue, toward Potomac Yard, before heading back toward Crystal City.
