Race Limit


For those who are completing the live Baltimore 2021 half marathon, here’s what you can expect:

The half-marathon start line is a party on the shores of Baltimore’s famed Inner Harbor, the 13-mile mark of the marathon. Complete with a live band  and 10,000 of your new best friends, this unique set up allows for the fastest marathoners and those attempting to qualify for Boston to pass and assures that the marathon champion will be the first to cross the finish line for the LIVE television coverage on WBAL-TV.  The half-marathon will run its own course for the first 3 miles and merge with marathon at Patterson Park. From that point, marathoners and half-marathon participants will run the same course to the finish line in Baltimore’s famed and iconic Inner Harbor!

1) Participants in the Half-Marathon must be at least 14 years old
2) Participants must be able to complete the course in 5 hours (22:54 min/mile pace)

Those who participate virtually, will have the option to run their own course wherever they chose! For more information on running virtually, visit HERE


When registering, all will have the option to sign up and run virtually. All virtual participants will have the option to upgrade to join the live event until September 15.

All virtual runners will receive their race premium and medal in the mail and be able to submit their times online.

  • I enjoyed running in the BRF Half Marathon. It was wonderful having so many Baltimore spectators cheer you on as you ran through their neighborhoods. 10 times better than [another Half Marathon in the  region]. I plan on running the BRF Marathon next year.

  • I very much enjoyed the post-race celebration village. The village was the cherry on top of the tremendous support we, as runners, received from the Baltimore community and its first responders. Kudos to all.

Walkers:  Walkers are welcome to participate in the CareFirst BlueCross BlueShield Half-Marathon. Please be advised of the following:

  1. Walkers will start at the back of the field in wave 5. If you plan to walk but have not been assigned to this wave, please start here anyway.
  2. Walkers must complete the half marathon course in the 5-hour time limit (22:54 min/mile pace). Any walker who does not keep this maximum pace  throughout the race will have the option of 1) getting on the SAG vehicle to return to the Inner Harbor or 2) or finishing the course off the road and on the sidewalks as a pedestrian.
  3. As a courtesy to runner participants, we ask that walkers not be more than two abreast so runners can easily pass.

Wave Start:  In order to maintain a comfortable and safe race experience for all participants, the CareFirst BlueCross BlueShield Half Marathon uses a wave start. Bib numbers will be issued based on expected finish time and will correspond to the holding pen you have been assigned. There will be five (5) holding pens and we ask that all participants adhere to this policy and start with their assigned wave. Please keep in mind that with the B-Tag system, your time will not start until you cross the start line.

Charity Groups:  The Baltimore Running Festival welcomes charity groups to utilize the event to fund raise and raise awareness of their cause. For more information on charity groups and the requirements involved, visit our Run for a Cause page or email [email protected].

Packet Pick Up

Live participants will be given the option to have their race bibs mailed to them in order to limit travel and personal exposure. All you have to do is cover the postage and handling fees. This option is offered as an add on during registration.

All live runners who do not pay for the mailing option are required to pick up their packets at our one-day Health & Fitness Expo held on Friday prior to race day. The expo is located at the Baltimore Convention Center. For more details, click here.


Runners participating virtually will automatically get their packet mailed to them and WILL NOT be permitted to claim their packet during the expo.

Chip Timing

The event will continue to utilize the best timing technology available. The B-tag technology offers runners a streamlined race experience with timing tags attached to participant bib. This method eliminates the need to scan your chip at the expo or to return the chip following the race, which means no more sitting down to undo your shoe lace just after your run and you no longer have to worry about a charge for a lost chip.

Tips to have your time accurately recorded:

  • Race bib is clearly visible on the front of the torso
  • Race bib is unaltered and unmodified (do not fold or wrinkle)
  • Race bib is pinned in all four corners
  • Race bib is not covered (jackets, runner belts, water bottles, etc.)

Virtual Runners: All virtual runners will be self-timed.  You will have the opportunity to print a race bib and report your finish time into the official race results. 

Medical Support

Our wonderful medical partner Medstar Sports Health is there for you, even during your virtual race.  Learn more HERE.

Once we return to a live event, MedStar Sports Health will provide medical support on the course and in the finish line area. The MedStar staff will include certified doctors, registered nurses, physician assistants and EMTs and will provide the necessary medical attention to any patient in need. We are grateful to have MedStar Sports Health associated with the event.
