This year's early-season ride is March 22. Same day as TriMania tho. (Pretty funny they name it apparently after their country's most comic-opera ship wreck):
Sat., March. 22
House of Sweden, 2900 K St. NW
REGISTRATION OPENS MON., FEB. 10
The legendary Vasa Ride is back! Choose from three route lengths, all departing from the House of Sweden in Georgetown: 15, 30, and 59 miles. The medium and long routes go up MacArthur Boulevarde and tackle Potomac, Md.'s rolling hills, while the short route stays within D.C. All riders return to the House of Sweden for traditional warm blueberry soup!
Would like to do this ride one of these years but I'll be at Trimania with the other 50+ DC Tri Club peeps checking out and getting some cool swag.
