The Ultimate Guide to Training for the D.C. Triple: 10 Miles to 26.2

For many runners in the District and beyond, the alluring D.C. Triple is a challenge well worth taking on. This spectacular event offers a unique opportunity to combine the Cherry Blossom 10-Miler, the Army Ten-Miler, and the Marine Corps Marathon within a running season. Those looking to complete all three in a single year will need incredible discipline to succeed, as well as a focused training plan in place.

The Challenge is Real

Each of the three races typically requires its own unique approach to training for athletes to be successful at the finish line. A Marine Corps Marathon training plan can certainly look very different from a Cherry Blossom 10 Mile training approach or how a runner might take on the Army Ten-Miler. While there are D.C. running clubs for marathon training that can be useful, they don’t always account for the distinct training needs it takes to finish all three of these races seamlessly. Those who want to stand out will need to master the art of speedwork in tandem with navigating the city’s hills and unpredictable weather.

The Thesis Fit Difference and Philosophy

Ultimately, training isn’t just about miles. It’s about biomechanics, metabolic efficiency, and recovery methods like our cold plunge in Washington D.C. that work. When you’re looking to step up your running game and take on the D.C. Triple, the team at Thesis Fit can help. We implement sports performance training, science-backed coaching, strength programming, and personalized diagnostics. These are designed to help athletes train smarter, not harder. Our goal is to help you peak at the right time for every race ahead.

Prepare for the Spring Phase: Cherry Blossom 10 Mile training

This is a race that requires speed, aerobic power, and race efficiency from runners. While the Cherry Blossom 10-Miler is a flat and fast course complete with gorgeous views, it also demands pacing precision to complete successfully. At Thesis Fit, we provide guidelines around a few key training priorities for this race that include:

• HIIT workouts and Interval Work
• Pacing Practice
• Aerobic Threshold Runs

Our interval work is a core component of this phase, while pacing practice allows you to rehearse your goal pace on a loop that simulates the race’s long stretches. The aerobic threshold runs we build into training are what you need to acquire enough stamina to hold pace for those full 10 miles without fading.

Getting You in Top Condition with the Thesis Fit Edge

When you work with Thesis Fit to prepare for the Cherry Blossom 10-Miler, the journey starts with a 3D body scan. This allows us insight into your posture, joint loading, and stride mechanics—information that’s vital before ramping up workout intensity. We take time to put together a training plan that optimizes your form and speed. This reduces the risk of injury, even as training volume increases.

Bridging the Gap During the Summer Slog

D.C. is a destination that’s known for its high temperatures, intense humidity, and endless sunshine in the summer months. These are factors that derail even the most motivated runner at times. At Thesis Fit, we know how important this phase of your running journey is when you want to complete the D.C. Triple. That’s why we help you refocus on transitioning from speed to endurance in the most difficult season of the year.

A Summer Training Strategy That Works

When you’re training with our team at Thesis Fit, you’ll discover we have a proven and successful summer strategy in place. Here, we focus on:

• Steady mileage that builds a strong aerobic base
• Long and slow distance work to prepare for marathon training
• Heat acclimation that gradually introduces warm-weather runs into your schedule

We always recommend runners focus on shaded and cooler routes this time of year to better acclimate to the conditions. Rock Creek Park and the C&O Canal Towpath often prove to be useful areas offering relief from the heat as well as terrain that’s good for long and steady runs. During this training phase, our team at Thesis Fit will make sure to target the knees, hips, and ankles of our runners. We believe that functional strength training is essential, and we aim to “bulletproof” your joints before those high-mileage marathons ahead.

Find Your Stride in the Fall Phase with a Marine Corps Marathon training plan

Fall is the season when everything you’ve been working on comes together. Many runners use the Army Ten-Miler as a good checkpoint for how they’ll fare in the Marine Corps Marathon. The time in between is ideal for test pacing, mental readiness, and fueling as well. If you utilize the Army Ten-Miler as a long-run workout, you’ll be better prepared for the key challenges of the Marine Corps Marathon two weeks later. Some of the more grueling features of the route will be:

• The 14th Street Bridge
• The “Mulligan Hill”

Where the 14th Street Bridge challenges runners with a long, exposed stretch of road, the “Mulligan Hill,” is a late-race climb that requires incredible pacing discipline and strength. At Thesis Fit, we assist athletes training for these hurdles with the help of our in-app nutrition coaching. This gives you great insight into gut training, including carb-loading strategies and fueling timing so you can power through that final 26.2-mile stretch knowing you’re in the best shape possible.
