Two weeks ago, I ran my first ultramarathon!
It was a 72-mile loop around Lake Tahoe. We started in Stateline, Nevada, and finished in South Lake Tahoe, California (less than one mile from each other, if Iâd only walked backwards).
We started at 7 p.m. There was another runner who had done it several times before there at the start, and I asked his advice. âIt really simple," he said. "Just donât quit."
Concise. Profound. The type of advice you can mentally process at mile 65 of a 72-mile race.
So if youâre someone who is interested in running an ultramarathon, or just curious what itâs like running one, keep reading for a glimpse into what itâs like to run for 18 hours straight.
The Ultramarathon Requires a Different Mindset
An ultramarathon isnât about speed, at least not for most people.
Itâs about the practice of just not stopping and the will to keep moving forward. From the get-go, we knew that we wouldnât be running the entire thing, especially not at 6,000 ft of elevation on a course with nearly 4,000 ft of gain.
Somewhat unique to this ultramarathon was that it was all paved, so not âtechnicalâ at all like trails. There were several major climbs where it was more effective to take a power walk than to force a slow, energy-consuming jog.
This was part of my âwhyâ for running this event. After not running for most of 2024 while being pregnant and making a comeback in early 2025, I didnât want to run a marathon and leave room to be disappointed that I wasnât as fast as I used to be.
This ultra was a new, challenging goal in one of my favorite places and it was always about just finishing, no matter what that looked like.
Training Looks Different
Training for an ultramarathon meant a lot of slow, comfortable miles to gain time on my feet. I had a few runs where I felt great and sped up in the last few miles, but there was never pressure for me to do so.
I knew weâd be running through the night, so I practiced one or two night runs to get to know our gear and mentally prepare for lots of miles in the dark.
I also practiced run/walk intervals from early on, even though it didnât feel 100% natural or comfortable. The ability to handle the physical starts and stops of the ultra was training in itself.
From my physical therapy perspective, the key was balancing the miles with smart strength work. My training included heavy posterior-chain lifts, single-leg stability work, and plyometrics to maintain power and resilience. I never skipped recovery weeks. Although my feet still feel as though theyâve aged 15 years, I was able to make it through training and race day injury-free!
Gear and Running Through the Night
Thereâs a whole other world that exists when youâre running through the night.
For the first 50 miles, the sun was gone, the temperature dropped, and the world was mostly silent except for our footsteps. There was no moon that night, so the stars were extremely bright.
Running in the dark is both eerie and peaceful. Perhaps it was the sleep deprivation or that I rarely looked at my watch, but those miles all seem to blend together in my mind when I think back to the race.
Pro tip: If you ever plan to race overnight, practice with your gear in training. Know how it feels to run with a headlamp or a chest light. Know what clothing layers work when your temperature fluctuates. My light only lasted about five hours, so I brought a power bank and an extra handheld light.
Fueling: The Real Key to Success
Fueling was everything.
During an ultra, nutrition becomes as important as pacing. I ran the first two-thirds of the race with a hydration pack containing Tailwind and LMNT. During the rest stops every five miles, I had water, PB&Js, Halloween candy, Layâs chips, chews, and pretzels. My goal was to stay slightly ahead of hunger and thirst, because once you fall behind, itâs hard to come back.
Perhaps because of that, my stomach never turned on me. Once the sun came up, I switched mainly to water and stuck to small, frequent bites of anything that sounded good.
Someone recently told me an ultra is like a âmoving picnic.â You really do have to eat early and often in order to sustain the energy needed to keep moving forward.
The Final 8 Miles
The last eight miles were brutal. The sun came up around 7 a.m., and there was one major climb with about 16 miles left to go. As the day warmed up, the bottoms of my feet really began to hurt. I remember passing the â8 Miles to Goâ sign and thinking how long that sounded. That was the only time I considered quitting and sitting on a boulder and waiting for someone to pick me up.
Even though I walked most of those last miles, I just didnât quit. It was never about finishing at a certain time, it was about making it.
In those moments, I thought about the months of training, the hours of mental preparation, and the 65 miles Iâd already run, and decided that quitting with eight miles to go wasnât how the story ended.
Slowly, each mile ticked by, and we crossed the finish line somewhere between 18 and 19 hours.
The Relief of Finishing
Iâve crossed a lot of marathon and half-marathon finish lines, but the relief waiting for me at this one was the greatest.
I think thereâs a mental flag you have to carry for months when training for a long-distance event. Itâs not only the running, but the unknown with how itâs going to go, what you need to prepare, whether youâll be able to complete the goal, etc.
Now, for the first time this year, Iâm able to have the satisfaction of completing the event and resting without looking forward to another 20-mile training run on the weekend.
Although my feet are still healing and running isnât quite comfortable yet, Iâm really proud to say I completed my first ultramarathon injury-free!
For anyone eyeing an ultra (or even a half or full marathon), prioritize the foundations - strength, mobility, sleep, fueling, and pacing. Theyâre not the glamorous parts of training, but theyâre what make these extraordinary distances possible!
Finishing Thoughts
Running 72 miles taught me that you donât have to run the whole time to make progress, and you donât have to break down to achieve something extraordinary. You just have to keep moving forward.
If youâre thinking about tackling a big goal, whether thatâs an ultramarathon or your first run back after injury, Iâd love to help you build the strength and strategy to do it safely.
