Riley’s Rumble Half Marathon 2021

May 1, 2021 @ 7:30 am - 11:00 am


Note detailed runner instructions will be emailed out on Wednesday, April 28th.


Registration will be limited to 250 participants for this event.  MCRRC members may participate in this event at a cost of $20.  *** PLEASE NOTE ALL MEMBERS MUST PRE-REGISTER FOR THIS EVENT TO SECURE A SPOT *** We understand that this is different, but it is necessary in order for us to be able to control participation and ensure we are within our permitted restrictions.

Registration for non-MCRRC Members will be available at a cost of $30.

Once the race is “sold out,” it is sold out – sorry, but we are unable to make exceptions due to county regulations.

Packet Pickup:

A drive-thru packet pick-up will take place at the MCRRC Clubhouse (14672 Southlawn Lane, Suite I, Rockville, MD 20850) on Friday, April 30th, from 5:00 until 7:00 pm. Your items (bib, chip & any shirt you purchased) will be passed to you in a clear plastic bag. Please have your bib number with you to speed up pick up and stay in your car and follow the cones to go through the drive-thru.

If you are unable to pick up your bag on Friday then they will be available on tables starting at 7:00 a.m., but please only come about 15 minutes before your start time to pick up so that we can follow our covid guidelines.

Start / Finish Area:

Please note that the start and finish of the race will look different than we are used to. Participants and volunteers will be required to wear a mask, properly fitted to cover both nose and mouth, at all times in the start/finish area of the race.

The start of the race will be conducted as a wave start, with a few runners starting every few minutes to allow for proper social distance along the race route.  Please note that you are required to start at the time you are assigned. The number of runners in each start grouping will be appropriate to local health regulations at the time.

Participants are required to maintain social distancing at ALL TIMES and upon finishing the race, return to their vehicles as quickly as possible. Please do not linger in the start/finish area.


Participants are encouraged to carry personal water for during the run. Water will be available to refill personal water bottles.  All finishers will receive a takeaway tote containing pre-packaged refreshments to take with you as you leave the race site.  As there will be no bag check, please keep all personal items in your car.


Restrooms will not be available.  Participants should plan to “go” before leaving the house or on the way to the race.  Additionally, we discourage the use of “nature” as doing so can not only make other participants uncomfortable, but if seen, can jeopardize obtaining future permits.

During the Race:

While masks are not required to be worn while running, they are required to remain on until participants cross the starting line. Please keep a face covering with you for use when passing another runner and during all times when social distancing cannot be achieved.

All participants will be required to put their mask back on prior to crossing the finish line. If a runner has lost their mask, a volunteer will have disposable masks to distribute as needed.

When at all possible, please refrain from purposely discarding your mask on the race route. This is not only considered littering, but is unhealthy exposure to others.


Spectators are prohibited from attending events in order to limit the number of people in attendance, comply with permit regulations and limit the risk of exposure to all involved.  If a friend or family member must accompany you to the event they are asked to remain in your vehicle during the event.

Health & Wellness:

Now more than ever, please pay close attention to your health prior to attending this event.  If you have been exposed to COVID-19 or another person with COVID-19, please stay home.  If you have cold symptoms, a mild fever, or just “don’t feel well,” we ask that you please stay home. All participants are subject to temperature checks at the discretion of our race staff.

Following the Rules:

Please understand that these safety measures have been put in place for the safety of all participants, race staff and volunteers and most are required under our permits and current county regulations.  Your participation in this event is optional – but the protocols are not.  Should these COVID-19 protocols make you uncomfortable, we would suggest you refrain from attending.  Race staff and volunteers have the authority to ask anyone not following safety protocols to leave the race site.
