Saturday's workout of 22 miles covered most of the Baltimore Marathon route. I joined hundreds of other runners on this course run, supported by Falls Road Running Store. Check out the route below, from mapmyrun.com. This service is awesome! It uses Google maps to calculate distance, is interactive (zoom, pan, etc, just like Google Maps) and even shows elevation. By getting an account, you can save routes and record them under your training log. Better yet, you can find routes that other people have saved. I love it!
