Run the Convention Center Stairs

This is a great spot to get in a workout and to get some fresh air. The stairs are around 100 steps to the top, so if you're feeling good, you can get a few rounds in. In terms of safety, there are usually people around the convention center, so you most likely won't be alone. With that said, be sure to check the Events Calendar; it can get a little too crowded if there's a big conference in town.

Once you're all finished up, head into the Gaslamp District for a bite.
