Lake Union is a Seattle landmark and namesake of several neighborhoods and streets in the city. A glacial lake, Lake Union’s basin was dug 12,000 years ago by the Vashon Glacier, which also created Lake Washington and Green Lake. Runners have been running around Lake Union for generations. The Lake Union Loop requires a full circumnavigation of the lake using the Fremont Bridge (western terminus) and University Bridge (eastern terminus) but runners may use any of the numerous paths and side streets to complete the loop.

Here's your chance to embark on a journey endured by former President General Ulysses G. Grant himself. You will literally retrace the exact trails that are still very much intact today that were utilized by Grant and his Soldiers as they advanced to attack Fort Donaldson on a pleasant day in Feb of 1862, a day that would go from warm and sunny to brutally cold, rainy and snowy within 24 hours.

Description: Since this is a loop, it may be run in either direction so long as you start the loop and finish at the number 22 sign.
