Pushing Beyond Your Body’s Limits.
Preparing for the Great World Race taught me a lot about endurance, recovery, and resilience. It also taught me that there is a fine line between being prepared and pushing beyond your body’s limits.
While the Great World Race itself involved running seven marathons on seven continents in seven consecutive days, the real challenge happened long before I arrived at the starting line. The months leading up to the event required more mileage, more time, and more physical stress than anything I had previously attempted. For runners researching ultramarathon training or preparing for a multi-day endurance event, it’s easy to focus on the finish line. It’s equally important to understand the realities of high-volume training and the risks that come with it.
Building Toward Peak Volume
My training wasn’t designed to make me faster. It was designed to make me durable.
The Great World Race demands a very different skill set than a traditional marathon. You’re not trying to maximize performance on a single day. You’re trying to perform well enough that you can recover and do it all over again tomorrow. That shift in focus changed everything.
As my mileage increased, so did the complexity of my training schedule. Mondays frequently included runs of 20 to 30 miles, followed by another substantial effort the next day. Midweek often involved double-run days intended to simulate the accumulated fatigue I expected to face during race week. The purpose wasn’t to chase personal records. It was to teach my body how to continue moving when every instinct suggested stopping. By the peak of training, I logged several weeks around or slightly above 100 miles of running, in addition to extra walking throughout the day.
For many experienced ultramarathon runners, those numbers may not seem extraordinary. For someone who had spent most of her running career training on fewer than 40 miles per week, however, it represented a dramatic increase and a significant leap into unfamiliar territory.
What People Don’t See About High-Mileage Training
One hundred-mile weeks sound impressive. What they really are is time-consuming.
Because I’m not particularly fast, every mile required a significant investment of time. Training often stretched across the entire day, with miles squeezed in before work, between meetings, after family activities, and late at night when everyone else was sleeping. Like many endurance athletes, I quickly learned that no major goal is accomplished entirely alone.
My husband carried a tremendous amount of extra responsibility during that training cycle. My kids tolerated a parent who seemed to spend an awful lot of time either running, stretching, icing, or talking about running. The truth is that endurance achievements may be individual on paper, but they’re often supported by an entire team behind the scenes. That’s one reason I have so much respect for runners balancing high-volume ultramarathon training with careers, caregiving responsibilities, and daily life.
The Importance of Recovery
One lesson that became increasingly clear throughout training was that recovery is not separate from training. Recovery is training.
For endurance athletes, easy days, sleep, nutrition, mobility work, and strength training are all part of the preparation process. The longer the event, the more important those pieces become. I worked closely with a physical therapist, sports medicine physician, and primary care physician while increasing my training volume. Strength work, mobility exercises, recovery protocols, and regular monitoring all became essential parts of the process.
I tried to do everything right. But sometimes doing everything right still isn’t enough.
When My Body Started to Push Back
As training volume increased, I began experiencing pain in my lower leg. At first, I assumed it was a classic case of shin splints. The discomfort became significant enough that I decided to begin my taper earlier than planned. While it wasn’t part of the original strategy, the additional recovery allowed me to arrive at the starting line feeling reasonably rested.
At the time, I thought the taper had solved the problem. It hadn’t.
After the race, I learned that what I believed was shin splints was actually a Grade 4 tibial stress fracture. In hindsight, the diagnosis wasn’t surprising. The training load had been enormous, particularly for someone with my history and underlying connective tissue disorder. The injury served as an important reminder that even the best training plan cannot eliminate risk when you’re asking your body to do something extraordinary.
Was It Worth It?
Looking back, there are certainly things I might do differently. Could I have reduced my mileage somewhat and lowered my injury risk? Probably. Could I have arrived at the starting line healthier? Possibly. Could I have completed the event with a more conservative training approach? Maybe.
The reality is that nobody truly knows how much training is enough for a challenge they’ve never attempted before. What I did know was that I understood the risks and made the decision deliberately.
The race itself was extraordinary. I completed the challenge, recovered fully, and gained an invaluable understanding of both my capabilities and my limits. That’s knowledge that can’t be learned from a training plan alone.
Finding a More Sustainable Approach
Ironically, after completing the Great World Race and eventually finishing a 100-mile ultramarathon, I’ve returned to a much simpler routine.
Today, my training looks far more like it did before this adventure. Most weeks include three runs, regular strength training, mobility and physical therapy work, yoga, easy cycling, and considerably more family time. I’ve come to appreciate that fitness isn’t always about doing more. Sometimes it’s about doing enough.
Many ultramarathon runners find themselves chasing bigger mileage, bigger races, and bigger goals. There’s nothing wrong with ambition, but I’ve learned that sustainability matters just as much as achievement. In fact, I now have more time for recovery, mobility work, and strength training than I did when I was running 100-mile weeks, and in many ways I feel healthier because of it.
Key Lessons for Ultramarathon and Multi-Day Race Training
If you’re preparing for the Great World Race, a stage race, or an ultramarathon, these are the biggest takeaways from my experience:
Train for Recovery, Not Just Performance
Running a marathon is one challenge. Recovering well enough to run another marathon the next day is an entirely different skill. Recovery should be part of your training, not something you think about only after workouts.
Prioritize Time on Feet
For multi-day endurance events, extended periods of movement can be just as important as weekly mileage. Walking, easy running, and simply spending more time moving helped prepare me for the cumulative fatigue of race week.
Practice Back-to-Back Efforts
Learning to move on tired legs became one of the most valuable components of my preparation. You don’t need to destroy yourself, but you do need to understand what fatigue feels like and how your body responds to it.
Don’t Neglect Strength and Mobility
Physical therapy, mobility work, strength training, and recovery practices were essential throughout my build. Without them, I doubt I would have made it to the starting line.
Respect Your Limits
More mileage is not always better. The goal is finding the minimum effective training necessary to prepare for your event while staying healthy enough to actually show up and race.
Looking Back
There’s no question that training for seven marathons in seven days pushed me further than any other endurance challenge I’ve attempted.
Would I do it again? Absolutely.
Would I approach parts of the process differently? Absolutely.
The experience taught me how much my body could endure, but it also taught me something equally valuable: success in endurance sports isn’t just about seeing how much you can take. It’s about learning where your limits are, respecting them, and finding the balance that allows you to keep doing what you love for years to come.
For me, that’s the most important lesson the Great World Race had to offer.
