Columbia Duathlon

This is a 45 mile biking event through all 10 Columbia Villages. You will also stop at 23 Columbia Association pools along the way to swim a couple of laps (however many you do is up to you). You can slide down the pool slides (if they are open) and take a dive. The ride is supported with 2 food stops along the way and technical support.

We can honestly say there is no event like this anywhere else!!! Please join us to benefit the Ulman Foundation.

10K Goal Race will be the Columbia Classic 10K race on the first Sunday in October

The Next Step Building to 10K Program is for runners of varying abilities. Participants will do a 2 mile time trial July 23 at Longfellow Elementary at 6pm so coordinators can group participants with those of similar abilities. Weekly training runs will involve a variety of running techniques including speed work and hill work to improve running performance. All runners should be able to run 3 miles before starting the program.

With August temperatures and humidity soaring, we are offering a great way to get a 5K run in! This indoor 5K takes place entirely inside the mall!

Perfectly timed with both Maryland tax-free week and back-to-school shopping, not only can you hit the halls of Arundel Mills, you can stop in for great specials at all of their retailer before or after your run!

Last race we had great specials from Hey Dude, Under Armour, Nike, Lindt Chocolate, Auntie Anne's, Medieval Times, Nandos, Merritt Athletics, and more! Stay tuned to hear who will be participating this summer.

Choose between completing multiple loops for the full 5K or opting for our family‑friendly fun run or walk, featuring a shorter distance perfect for kids and new runners. This race takes place before the mall opens! It won't be a great course for setting a personal best, but we can promise it will be a fun and unique one!

All finishers will receive a medal.

This race is hard capped. If you can still sign up, there is space! Once we hit our cap, we will have to welcome you next year! Strollers are only allowed during the Fun Run/Walk

Sunday Morning Check-In Time:

Elite Runners: 8:00 AM

5K: 8:40 AM

Fun Run/Walk: 9:45 AM

Post-Race Activities!

After you cross the finish line, stick around for post‑race activities, including fitness demos, recovery stretches, training tips, and workout ideas for all ages.

Packet Pick-Up

Bib, swag, and shirts will be handed out before the race! If you have not received it, please arrive by 7:30 AM for Elite Runners, 8:00 AM for the 5K, and 9:15 for the Fun Run/Walk.

Reminder- this is a cupless race! Waters will not be handed out. We have dozens of water fountains on site and want to ensure the floors stay as dry as possible. Please bring a container with a lid for your water.

Swag and Giveaways

All participants receive both a finisher's medal and a shirt! Check in for the swag bag our retailers and partners provide, including giveaways, raffles, promos, and discounts at Arundel Mills stores! Shirts are not guaranteed for runners who sign up after 8/1.

Hydration Station

In order to keep the floors as dry as possible, there will only be a water station at the start/finish line that racers will pass as they go around the mall. While water/drinks are allowed on the course, there will be no water cups while on the course except for water at the food court. The mall has several restrooms available throughout the course that have water fountains. Running with a cup without a lid is not permitted, but running with water or other fluids is permitted as long as it closes (water bottle, camelbak, sports bottle, etc.)

What to Bring

Your own water, bags, and gear are fine to bring! We will have waves starting/finishing in the food court that will provide plenty of tables and chairs to store your items. We cannot allow pets, selfie sticks, glass, or weapons. Note that neither Arundel Mills nor Peake Events is responsible for lost belongings.

Parking and Entrance Recommendation

The closest parking would be the Maryland Live Casino parking garage (free), and use the Food Court Entrance. Nando Peri Peri is located next to that Food Court entrance for reference.

Distance Disclaimer

Please note: Course distance and start times may adjust slightly based on registration numbers and logistics. Waved starts will help ensure plenty of space for running through the mall corridors. The 5k course will be four laps around the mall and is ~1/10th of a kilometer longer than an exact 5K.

Strollers and Children Note

The 5K race will have runners completing four laps around the mall, making for tight spots, especially in two sections that require a small ramp to go up/down. Runners can also opt to run up and down the three stairs as they see fit. Strollers will only be allowed during the Fun Run/walk and must start at the back. Any child participating in the 5K should be able to maintain a jogging pace and stick to the right-hand side of the course. We love kids, but know they like to take off and run around without always looking around their surroundings. Please ensure your child is both old enough for the 5K and can follow proper race etiquette. We invite everyone to join the Fun Run/Walk!

Please join us on our 4th Annual All Clubs Ladies Ride to shine a light on Heart Health. The cycling community in Maryland along with some of our sister clubs in surrounding areas have come together this year to do one all clubs ladies' ride to show solidarity across all the clubs. The theme for this year's ride will be Heart Health as heart disease kills more women than ALL forms of cancer combined and also kills more than 50,000 women of color annually. The event rolls rain or shine. We will be at Pavillion West.

In honor of Heart Health, we are asking all women to wear red.

Lunch will be provided and there will be Vegan and Vegetarian options available

Registration includes: Lunch, Rest-Stop Refreshments, T-shirt, and a charitable donation.

T-shirts will be available at registration pickup to all participants who register prior to August 13, 2026. After that date, t-shirt availability will be on a first come first serve basis based on what we have left.

There will be 2 ride distances: Approximately 33mile and 21mile

We want everyone to return close to the same time so we ask that you pick your route accordingly based on your skill level. There will be SAG provided for the both routes; however, SAG will be for bike malfunctions only. Please make sure your bike is in good working order prior to the ride. There will be bike mechanics on-site prior to the ride so if you are unsure of the condition of your bike, we encourage you to get it checked prior to the ride if you have not already done so prior to the day of the event. These mechanics will be available on a first come first serve basis and can not guarantee they can repair all bikes prior to the start of the ride. There are a few rollers and we want to make sure everyone rides and returns safely. You are responsible for having your own tire change supplies as SAG will be there to assist with tire changes and mechanical issues only. If you have not been riding your bike but still want to participate in the ride, please be on the lookout for clinics

that will be held prior to the event.

PLEASE CHECK BACK CLOSER TO THE EVENT DATE FOR UPDATED ROUTES
