When we're looking to go for a real run, we always head straight for Memorial Park. As one of the largest urban parks in the United States (it spans 1,466 acres), Memorial has everything a runner needs. The three-mile loop along Memorial Drive is always a fun place to run since you can count on some solid people-watching while you work on getting your miles in; the path has plenty of water fountains and bathrooms, and it's well-lit so you don't have to pack it in as soon as the sun goes down. At the same time, there are plenty of other running paths for those who like to get away from the madding crowd, and the park boasts a variety of trails for more nature-oriented types, so no matter what sort of running (or enthusiastic walking) you're in the mood for, you can get it done at Memorial.
