The annual Summer Kick-Off Party! The Baltimore 10-Miler returns to Druid Hill Park just outside the Maryland Zoo. A challenging yet fair course, the 10-Miler takes participants through parts of Baltimore that are often not appreciated when driving through them. The premiums for this race never disappoint and the post-race party is a great reward for completing the race– complete with cold towels, fresh watermelon and icy craft beer to enjoy while listening to live music on the spacious lawn of the zoo.
