Runners love Fredericksburg -- a great spring weekend getaway. Run through this historic town and earn epic street cred by scaling Hospital Hill at the 10th anniversary Historic Half. Shops, restaurants, historic sites and the Healthy Lifestyle Expo. Knock out a quick five miles, as part of the Semper 5ive presented by Navy Federal Credit Union. The five-mile run held the same day as the Historic Half includes Hospital Hill and ends with a star-studded medal.

Limited Spots Remain Are you an overachiever?  Did you always seek out extra credit in school? Here’s your chance to exceed the norm, again. Run the Devil Dog Double. It’s the Historic Half + Semper 5ive. One Day. Two Distances. Three Medals.

How many miles can you run in 100 minutes? Find out at the Quantico 100 presented by GEICO Military, a centennial celebration for the Base. Individual competitors or teams will log as many miles as they can in the allotted time. Special discount registration for Active Duty. Sure, there are lots of mud runs and wild racing challenges. But Run Amuck presented by Camelbak stands alone as the hands-down, push-yourself, have-a-blast, good-times-for-all, make-a-mess, must-do event. Its all parts fun and just enough run.

Serious about competing in a triathlon this year? Add the Quantico Tri to your calendar of events. Open water swim. Awesome bike course on Base. Run finishes near Officer Candidate School.

So by the transitive property, or something like that, if you run the  Quantico 12K, you will feel like a Marine.
