The Bike - 40K

The Nation’s Triathlon bike is a flat and fast design.

The one-loop bike course will speed you up and down the vistas and views of Rock Creek Park and Clara Barton Parkway along the beautiful Potomac River. Based on feedback from our athletes in 2008 the course has been changed to reduce the number of turns so that there are more straight-aways on wide smooth roads perfect for the aerobars. With all of the roads closed to traffic this is truly one of the most spectacular Olympic distance bike courses in the country.


According to a 2008 Participant:

"I’ve done a ton of triathlons (including twice at Nation’s) and must say the bike course this year was one of the best I’ve ever ridden."
