Careth Arnold

For @i.careth , motherhood and ultra running share more than meets the eye. Both ask for presence, resilience, and a willingness to adapt along the way. A reflection on movement, motherhood, and meeting yourself where you are. Video — @tonywithasony

What does it mean to be a mother? The first thing that comes to mind is unconditional love. As soon as my first child was born, it hit me with a zealous passion deep in my soul. This was a love I had yet to experience; it was a life-giving love—unconditional, patient, kind, fierce, and all-consuming. Yes, there are definitely moments when this love does not come easily. I am human, selfish, and far from a perfect mother. But God knows I try, and I am better for it. Please kiss your momma back this Mother’s Day—I sure wish I could kiss mine. Tell her you love her, even when she is frustrating in all her imperfections. Love sees past all of it. 🫶🏼 Thank you @somerrunner for capturing this moment at the Canyons 100k finish line! #happymothersday #kisses #motherlylove

Let’s recap my nutrition at the Canyons 100k this past weekend. I don’t normally talk about my race nutrition because I historically haven’t been great at it. But I think I’m starting to get it right. 🙃 Lately I’ve been loving the Näak Boost line of gels and hydration mix. I couldn’t have done it without an average of 60grams of carbs/hour consumed through 12 boost neutral gels, multiple flasks of boost hydration mix, 3 peach tea caffeinated gels, and an awesome squad who made sure I had what I needed when I needed it. One of my main goals for this race was to fuel well. I have historically struggled to consume adequate carbs in the back half of my races. But this past training block I put the effort in to train my gut to be more consistent with nutrition consumption and fuel my runs sufficiently. I felt so fly. Thankful for näakbars for helping me fuel my ultra! 🫶🏼😋 #nutrition #FuelYourUltra #Canyons100k #näak #sportsnutrition

CARETH ARNOLD — CERTIFIED BEAST Last year’s TDS champion brings home a strong runner up in today’s Canyons 100k. Leading early, Careth fought through a tough final 20 miles to bring home a proud 2nd place. Importantly, Careth DECLINED the Golden Ticket to Western States and will instead focus on Hardrock. We are on roll-down watch. 👀 Congrats, Careth! 📸: @ryanthrower #TrailCulture #canyons100k

Had a blast running hill repeats with the RUFA community in Moab. It was such a fun, beautiful, and challenging event. A solid test of fitness that helped build back my confidence after a rough first quarter of the year dealing with a revolving door of sickness. It was great seeing familiar faces and a showing of strong mommas @leah_yingling and @rachelraedrake ! So amazing. 🤩 Special thank to @shitinthewoods for not only capturing the moments but bringing out their glory and grit. 📸👌🏻 @runningupforair #stayoutthere #moab #rufa #TeamAltra #runstrong motherrunner

There are days when everything aligns: effort, terrain, and timing.⁠ ⁠ In 2025, @i.careth faced TDS, one of the most demanding and technical ultra-trail races in the world. From the first step to the final kilometer, she moved with focus, strength, and determination, navigating every climb, descent, and challenge the course presented.⁠ ⁠ By the end, she claimed victory in a race that tests every aspect of an athlete, physical, mental, and emotional. This was more than a win. It was a demonstration of what happens when preparation, presence, and courage come together in perfect harmony.⁠ ⁠ Careth’s performance at TDS is a reminder that excellence isn’t given, it’s earned, step by step, moment by moment. In 2025, she showed the trail-running world the power of belief, perseverance, and showing up fully, even when the mountains demand everything.⁠ ⁠ #ultratrail #fuelyourultra

Thailand holds space in my heart. It’s my country of birth and where I spent the first 15 years of life. I chose to race here the last couple years because it’s a homecoming of sorts. A journey that reminds me of my childhood. I have lived multiple lives since then and never thought I would be back 20 years later as an athlete racing 160+ km through the northern hill country. This race was the most challenging of the year. A solid ending to the season. The course is diverse and makes me think of adventure racing at times with its relentless presentation of obstacles. I traveled out a day before the start, crew less, not rested, but ready to go. And I went, until my body began to protest. I found my limits during this race and preserved with every last drop of my being- dynamite exploding in the pain cave. I lost significant time to the first woman in the back third due to the inability to descend quickly, but found victory in every step. I am a better athlete for it and have gleaned once again from my mistakes and will adapt. I am stoaked to have overcome such a journey at the end of a big season. Looking forward to bigger challenges to come, 2026 baby!! 👀🏔️ A special thank you to those who support me. @altrarunning @ultraspire @naakbars @nblaes Y’all da best.

A weekend spent camping with the family in Moab- I jumped into the Dead Horse 50k last minute to see how my legs would turnover in the middle of a big training block. Overall felt strong- enjoyed the red earth, slick rock, sunshine, and race community. My goal was to run a fast yet moderate race to insure I had some legs for my long run the next day. Content with the results- brick by brick we build. 💪😊 3:56 F1 and 9th OA #TeamAltra #motherrunner #FuelYourUltra #inspiredbyathletes #graceandgrit #deadhorseultra #moab

The end of the second loop and the end of my Javelina race. Details in previous post. Thank you @_kristennelson for capturing this moment.💛
