A fan favourite from 2025 was @bethgmckenzie’s incredible family support 🫶🏼

All the fuel, fishing vests, kids on board - they had it all! We love seeing it become a weekend for the whole family to get involved.

Don’t forget to lock in your support crews - it’s a team effort at #UTA! 💪🏼 by @bethgmckenzie

😅🔈My kids have very high standards…

They weren’t sure why I wasn’t winning the ASICS Bolt 5km. Apparently Wynne started to cry while spectating because the lead pack had pulled away from me. 

Hopefully, my smile and finish showed them that I WAS DOING THE DAMN THING…and sometimes, that is more than enough. Showing up for hard things, on a big stage, when the odds are stacked against you is something to be proud of. And I hope that is what they remember.

👋 New Profile Pic & (re)Introduction:

There are a lot of new friends here, so I wanted to re-introduce myself & welcome you to this space where I share my perfectly imperfect life.

I’m a 44-year-old 
👯‍♀️Mom (of Wynne-10, Marlo-6)
👰‍♀️Wife (to @imlukemckenzie)
👩‍💼Entrepreneur (Co-founder/CEO @wynrepublic)
🚴🏼‍♀️Former professional triathlete
🏃🏼‍♀️newly infatuated ultra-runner

🇺🇸I grew up outside Philadelphia and played east-coast-preppy-girl-sports (field hockey & lacrosse) until I went to Vanderbilt University. After undergrad, I made my way to CA and worked in PR in Beverly Hills before returning to grad school for my Ed.S. In educational Psychology.

👩‍💻My career as a Psychologist took a left turn when I took a leave of absence to pursue pro triathlon in 2013. 

🦘Triathlon brought me to my husband and to Australia, where we planted roots and currently reside in paradise- Noosa, Queensland, Australia. 

🏆My pro triathlon career was filled with astronomical highs & crushing lows. My proudest achievement was winning Ironman Switzerland when Wynne was just 13 months old. 

🤰In 2017, Luke and I founded WYN two weeks before our second daughter, Marlo, was born. I wish you could see me stamping mailer bags 9 mo. pregnant on the floor of our sketchy airbnb or answering our first customer service emails between contractions in the hospital. 

⏩Fast forward to 2024 & I’m a retired triathlete with a serious ultra running hobby. At 42, I ran my best marathon in 2:37 but then got itchy to go longer. In 2024 I completed my first two 100km trail races and now I’m in deep 😍. 

📈 At WYN, I’m the big picture person and steer our mission to make a positive impact in the endurance community. I also do all our In-Line design, act as CFO and am the Creative Director. 

🤍Family & work always come first, but I love this little grid where I share my passion for endurance sports and connect with you.

💁‍♀️I sponsor myself. If I’m going to send you chasing a link or show off a product, it’s going to be one of ours @wynrepublic because I create them and love sharing them.

🪦RIP playing it cool 

💭A little social commentary on what it's like to be a woman, mother, older athlete, 'influencer' and all the other things. 

❤️‍🔥 It's easy to feel judged in our 'too-muchness', but oh, what a tragedy it is when we force ourselves to be less. 

🥤Not that everyone needs to see me in a bikini every day- but the amount of times I've sent a very normal photo to my friends saying 'Is this too thirsty to post?' (And I always deem it 'too thirsty') ..When it's just me doing heat training or hanging with friends .. often makes me think - 'I bet literallly zero men text this to their friends if it's just a photo of them doing a normal activity'. 

✨I digress. I just hope that more strong women out there start showing themselves and the world that it's ok to be fast, loud, clumsy, hot, weird, hungry, serious, not-so-serious, ambitious, supportive, funny, independent, shiny, and YOU. by @bethgmckenzie

We caught up with @bethgmckenzie - elite level ultra marathon runner, the CEO of @wynrepublic , and a loving mother to her two daughters.

Living such a busy lifestyle, planning is extremely important to allow Beth to fit training, family time, work and recovery into each week.

As recovery plays such an integral part of Beth’s routine, her go-to is a quick express protocol after a run in the morning before her busy day begins, or during a lunch break to help her re-energise before the afternoon school run. taken in Noosa Heads, Queensland by @bethgmckenzie

How many bandanas can you collect @trailcontahoe ?

(The answer is eight). 

Scroll for moments from Western States week 2026! 

New Substack on the epic week: 'If you can't race 'em, pace 
'em' - link in bio! 

Once my legs had recovered from the race, I took Luke on a Broken Arrow loop. We're not in Noosa anymore! 

Luke 'is this the top?'
Me, 'it's one of the tops 😬'

Crew meeting for @daniel.c.jones - 3x top 5 @wser finishes in the past three years meant things were dialed and we were ready for a big on! 

If you can't race 'em, pace 'em. My thoughts on this and the entire week in my Substack (link in bio). 

Just before go-time @wser . Hoka lit up the mountainside with each athlete's name and number, which was really special. 

The one and only Sally McRae. You probably already follow her, but it you don't, you should! My queen of inspiration @yellowrunner 

The start of the Western States Endurance Run 2026. One hundred miles from Olympic Valley to Auburn, CA. (It's like triathlon's Kona)

SWAP!! Super coaches and friends @drmeganroche & @mountainroche cheering on athletes at Robinson Flat (mile 30). 

Waiting for a mate. 
Chilling in the ACG lounge awaiting Dan at Foresthill... ready to jump in and pace the next 18 miles. 

Dan was in a rough spot, but got going out of Foresthill after a reset. I was so glad I was with him. 

Cal street! Seeing this iconic section of the course was a dream, but it wasn't a dream day for Dan. He struggled with relentless gut issues as was forced to walk/hike/jog nearly the whole way. I had a front row seat to true grit and courage. 

Forging ahead. 💪🏼💪🏼

Iconic. 

Jennifer lichter made history and set a new women's course record of 15 hours 28 minutes in her 100-mile debut. Her story has moved me to tears several times - a brief introduction to Jen in my Substack (link in bio). taken in Palisades Tahoe by @bethgmckenzie

After an incredible week in Tahoe tor Broken Arrow, TrailCon & Western States, we've landed back on the east coast for some slow-down family time on the Sassafras River. 

Running here is always a good challenge: Classic East Coast summer heat wave, zero hills, and no trails will make for a 'creative' block in the lead/up to OCC, but there are plenty of opportunities to get fitter. 

I'm still processing the week that culminated in a record-breaking day at Western States. So many emotions in that experience and it was incredible  to see the 'Kona' of the trail world. Yes, I (desperately) wish I had been on that start line, but I was able to compartmentalize it and truly just live in the moment for love of the sport. Each story of triumph and defeat was so special and moving- I'm more motivated than ever! More on that soon. 

For now, you'll find me in the cornfields 🌽

Fit to fly 🪽🤍

My race day kit of choice for 46km and 9000 ft of climbing in the Sierra Nevadas at Broken Arrow Skyrace. All the pockets, all the white hot vibes. Time to get dirty! 

Featuring @wynrepublic 
🪽On-Call Crop (allll the pockets!) 
🪽Pace shorts 
🪽500ml WYN flask
🪽WYN Active Socks
🪽Aeroshield Wind jacket (for warm-up)

This kit choice allowed me to go with a hydration belt, as I was able to stash gels and phone in my top, eliminating the need for a full vest. 

How lucky am I that as 'Co-Founder/CEO', I also get to be 'athlete'? Putting all of our products to the test is my favorite part of the 'job'. These ones passed with flying 🪽 colors. taken in Palisades Tahoe by @bethgmckenzie

🦸‍♀️mini superhero cape forevermore.

Please enjoy our halfway aid station from @brokenarrowskyrace 46km .. it was a hot one so cooling was important- thanks to @imlukemckenzie for being on top of it all and to @precisionfandh & @jonnytye1 's mum who sewed these original mini superhero capes (aka ice bandanas)

🤍 as always, dressed by @wynrepublic wearing pace shorts & on-call crop in white.

⛰️Broken Arrow 46km - 10th 5:21 2630m+

❤️‍🔥As expected, I am still madly in love with the mountains, but they continue to play 'hard to get'.

⚡️But, I felt truly alive every step (even while simultaneously feeling like I might die) . How lucky are we to find our edges and suffer in a challenge of our own choosing? 

💭I'm proud of myself for showing up and giving my all. I traveled across the world this week with my little Aussie beach lungs and raced some of the world's best mountain athletes (some half my age). I dug in, never gave up, and loved (almost) every step. Congrats to all of the incredible women up there today- what an absolute show! 

🤍 Forever grateful that I get to do this, maybe not 'for a living', but at least as a partial business expense. p.s. buy my fit @wynrepublic taken in Palisades Tahoe by @bethgmckenzie
