Editor's Note: This article was published in 2017. WHOOP now operates on a subscription membership model, which is required to use the device and access data. Pricing and features have been updated since this article was written.

On Sunday November 5, WHOOP Senior Product Designer Tom Rand completed the New York City Marathon. It was Tom's first marathon, and he intended it to also be his last. He describes himself not as an athlete, but as simply a "regular guy." His only goal was to finish, which he did in 4 hours, 25 minutes and 20 seconds.

For most first-time marathoners, the journey to 26.2 miles is about more than just logging miles. It's about understanding your body, adapting to its signals, and making smarter decisions along the way. This guide walks through the key phases of preparing for your first marathon, using Tom's experience and WHOOP data as a roadmap for training smarter, recovering better, and crossing the finish line with confidence.

The inspiration: Deciding to run your first marathon

Running a marathon was never something Tom expected or even wanted to do–until he started working at WHOOP.

A native of Far Hills, NJ, Tom mostly played team sports growing up, hockey in particular. Running was not on his radar. In July of 2016, Tom started at WHOOP.

Shortly after, he volunteered to compete on the WHOOP team in a 203-mile Ragnar relay race. "I didn't really know what I was getting into," Tom said. "But I was the new guy in the office and I didn't want to say no. The relay was really tough and I wasn't prepared for it at all, but it got me into running."

It wasn't just that race that put Tom on a path to running a marathon, it was also his experiences interacting with WHOOP members. Understanding who members are, the challenges they face, and what they are looking to accomplish is essential to creating and maintaining a quality product. Not only has this helped Tom be better at his job, it's affected him on a personal level as well:

Tom decided to try a half marathon, with the goal that if he finished in under two hours, he'd sign up for a full. "I trained smarter than I ever had before," he said. "I broke the two-hour mark–barely, but I did it."

From there, it was just a matter of choosing which marathon to enter. "Since this was probably the only marathon I'd ever run, I wanted it to be a big one," Tom said. "I remember watching NYC as a kid, so I figured why not."

Building your marathon training foundation

A successful marathon starts months before you reach the starting line. While every runner's plan is different, most marathon training programs are built on a few key principles. Your training will likely be a 16 to 20-week journey that balances building endurance with crucial rest.

Key components of your training will include:

• The Long Run: Typically done once a week, this run gradually increases in distance to prepare your body for the full 26.2 miles.
• Recovery Days: Just as important as your runs, rest days or active recovery days (like walking or stretching) allow your body to adapt and get stronger. Pushing too hard without adequate recovery is a common path to injury.
• Tapering: In the final two to three weeks before the race, you will significantly reduce your mileage. This allows your body to fully recover, store energy, and arrive on race day feeling fresh and ready.

The goal isn't just to follow a plan, but to adapt it to your body's signals—something WHOOP is designed to help you do.

How to use data to train smarter and prevent injury

Tom began training seriously early last summer, but he didn't let it compromise other things he wanted to do. In late July, he went on a week-long Florida fishing trip with several of his friends. As can often be the case when on vacation, alcohol consumption was brutal for his Recoveries:

"I'd been training hard before the trip, but then did nothing for the entire week," Tom recalled. "It was really hard to get back into my routine after that."

One of the other major components to Tom's job is helping create the tips that appear in the WHOOP app alongside your data:

This led to an unusual "Ah ha!" moment during his training. "Earlier this fall, there was a time when I hadn't been drinking at all and I'd been sleeping really well," Tom said. "I thought I was doing everything right, but my Recovery was tanking. I opened the WHOOP app and the recommendation read 'You can get away with this training load in the short-term if you balance it later with lots of rest.' It made me confident that I was still on track as long as I didn't continue to overtrain. The crazy part was, I was actually listening to my own advice. When I originally built it, I never expected it would apply to me."

To no surprise, Tom's hardest training came in the month prior to the marathon. It was a bit of a juggling act for him to maintain it amongst other commitments:

"I had weddings two weekends in October, so I scheduled my hard runs on the Friday mornings before. Looking at my data, you can see with those two weekends in particular I got killed [10/14 and 10/28]. The challenge was focusing on recovery from training in order to be ready for the next week, while also having a good time at the weddings."

Outside of those two weekends, Tom did an exceptional job balancing his Strain and Recovery leading up to the race. This is the core principle of data-driven training: using your Recovery score to guide when to push hard and when to pull back.

When Recovery is high, your body is ready to take on more Strain. When it's low, prioritizing rest prevents injury and allows adaptation to occur.

Nailing your nutrition and hydration strategy

Fueling your body correctly is as critical as any run in your training plan. Marathon training demands a significant amount of energy, and what you eat and drink directly impacts your performance and Recovery. Focus on a balanced diet rich in complex carbohydrates for energy, lean protein for muscle repair, and healthy fats.

Hydration is also key. Dehydration can negatively affect your performance and increase your risk of injury. Make sure you are drinking water consistently throughout the day, not just during your runs.

You can use the WHOOP Journal to track how different foods, hydration levels, and meal timings affect your Sleep and Recovery scores. Over time, you can identify patterns and build a personalized nutrition strategy that helps you feel and perform your best.

Preparing for race day: The final week

During the week prior, Tom cut back his training load and tapered for the big day. Tom also did his best to improve his sleep consistency and get as much rest as possible in the final days before the marathon:

By prioritizing sleep, he ensured his body was fully recovered and ready for the immense Strain of the race. The Sleep Planner can be a valuable tool during this final week, providing nightly recommendations to help you meet your sleep needs and maximize your Recovery score for race morning.

The race day experience: A first-timer's WHOOP story

Tom logged a 20.7 Strain while completing the New York City Marathon. For him, it was the equivalent Strain of a professional triathlete competing in the Ironman World Championship, and a serious Ultra runner's third-place finish at the Wasatch 100.

Roughly three hours into the race (around the 20-mile mark), Tom's legs cramped up and he was forced to slow his pace dramatically, from 9-10 minute miles to closer to 12. You can see the exact moment this happened in his heart rate data:

This experience is common for many first-time marathoners. Pacing is a challenge, and even with perfect training, race day can present unexpected hurdles. Monitoring your heart rate zones during the race can help you manage your effort and avoid going out too fast.

Tom was also quite amused by the message he saw in the WHOOP app afterwards:

Post-marathon recovery and what comes next

Crossing the finish line is an incredible achievement, but your marathon journey isn't over. The post-race recovery phase is essential for preventing injury and allowing your body to heal from the significant stress of running 26.2 miles.

In the days following the marathon, your body will need rest. Expect to see low Recovery scores and elevated resting heart rate and respiratory rate.

Prioritize sleep, light activity like walking, proper nutrition, and hydration. Avoid intense exercise until your Recovery score returns to the green, signaling that your body is ready to take on Strain again. This is a time to celebrate your accomplishment and give your body the time it needs to fully recuperate.

Your partner in performance

"It was an amazing feeling to finish," Tom said. "I remember thinking in that moment, 'There is no way I will ever do this again.' But now that some time has gone by, I'm starting to wonder if I might try another one. I'd like to beat four hours, I was on track to do it for most of the race."

Don't be surprised if his continued interaction with WHOOP members helps him find the motivation to get back out there. Tom also believes his experience running the marathon will allow him to better serve our member base in the future:

"Going through a proper training plan and running the race gave me a much higher level of empathy for our members. To get out there and actually do what so many of them have described to me in person–it brought me that much closer to understanding their day-to-day lives."

Whether your goal is to run your first marathon, set a new personal best, or simply build healthier habits, understanding your body is the key.

Frequently asked questions about the marathon

What is the original story of the marathon?

The marathon was inspired by the legend of Pheidippides, an ancient Greek messenger. In 490 BC, he is said to have run from the battlefield of Marathon to Athens to announce the Greek victory, a distance of roughly 25 miles. After delivering his message, he collapsed and died.

What are the six Abbott World Marathon Majors?

The Abbott World Marathon Majors is a series of six of the largest and most renowned marathons in the world. They are the Tokyo, Boston, London, Berlin, Chicago, and New York City marathons.

How long does it take to train for a first marathon?

Most marathon training plans for beginners last between 16 and 20 weeks. This timeframe allows for a gradual increase in mileage to build endurance safely and helps reduce the risk of injury.

What is the biggest mistake first-time marathon runners make?

One of the most common mistakes is starting the race too fast. The excitement and adrenaline of race day can cause runners to exceed their planned pace in the early miles, leading to fatigue and cramping later in the race. Using a heart rate monitor to stay within your target zones can help you maintain a sustainable effort.
