Did some online research on the GW Birthday Marathon and here is what I found:
* Course: Three-loop course through Greenbelt, Maryland and the U.S.D.A. Beltsville Agricultural Research Center. USATF-certified, Boston Marathon qualifier. Course map here.
* ten aid stations, at approximately the 2.4, 5.8, 7.9, 9.7, 13.2, 15.2, 17.0, 20.4, 22.5 and 24.3 mile points. Water and Gatorade at all; GU at many
* They have a post-race party
* the last 1.2 miles of the course are straight uphill
* Easy to get in and out of
* race day packet pick up,
* reasonably priced,
* nice long sleeve tech tee,
* good organization,
* great volunteers and plenty of water/Gatorade stops.
* post race food and drink were amazing.
* organized by DC Road Runners Club and is one of the longest continuously held marathons in the United States
* some years it's been bitterly cold. with temperatures in the high 20's and strong winds, windchill will likely be in the teens. We urge all runners to bring plenty of layers, and to be prepared for the cold.
* Race starts at about 10am, so you can sleep in a bit (last year it was about 40 degrees)
* It's a small marathon
* Lots of people seem to use it as a training run for longer races.
* Runners share roads with vehicle traffic
* personal audio is strongly discouraged; they ask that you 'keep the volume down if you must.'
* For the first time, this year, bus service will be available to and from the Metro starting when the metro opens. Look for a Chariots for Hire mini bus with a "GW Marathon" sign.
