2026 pinned tweet: I help great brands show up in endurance, health, and outdoor culture in a way that actually fits. Host of @ForTheLRPod + @LongRunLabs. I build creator networks, design sponsorships, and connect companies with the runners, athletes, and builders who shape the space. Think: storytelling > ads. Community > impressions. Long-term > one-off deals. I also advise and invest in early-stage companies. If you’re building something in running, health, or the outdoors, we’re probably aligned. Oh, and I run a lot. Trails, preferably.

@echoghi @d9monti @Vinnymauri carbs, shoes, miles

@d9monti @Vinnymauri What is going on this year

A mind-blowing marathon debut for @Vinnymauri at the Mercy Health #GlassCityMarathon in Toledo: 2:05:54. . USA debut record . #3 USA all-time on record-eligible course

@iiiitsandrea @jesseandbens these are so good

This brand is now at Target (apart from Whole Foods) @jesseandbens It’s getting easier and more accessible price wise to find seed oil feel products all across.

@timgecko @mounttocoast Some of these guys are training for those too! Different strokes for different folks.

@JWLevitt @mounttocoast Why not just run an ultra? 100k and 100 milers on trail much more enjoyable.

2 Marathons. 1 Day. 52.4 Miles. We started at the finish line at 3am and ran all the way to the starting line, just in time for seven of us to turn around and run the official race. This is the "Double Boston" with the @mounttocoast crew. Why? "Because we can."

@kuperhale I must know more 🍿

Priming my engine to shit on every talking head that’s about to make a terrible take on brand marketing today after London 💆🏻‍♂️

@a_weisen @Scienceofsport I’ve explored this both via @insidetracker data and with other experts. I believe @MountainRoche has weighed in on this as well. If we were going to see issues, we’d see them. The issue wouldn’t linger. Here’s the first part insidetracker.com/a/articles/do-…

@Scienceofsport Just wondering the long term effect on health such as insulin tolerance and all the amateurs that are likely to follow suit

And if you watched the broadcast, then by the paired eyeball test implemented by Noakes (2026), you would have estimated 100-120g per hour. Good that it’s confirmed. Humans don’t run that hard for that long on belief, and no carbs

@UltraRunnerPod We’ve moved on from super shoes. We’re onto super duper shoes. Keep up!

I'd love to see a mile or a 5k held on a dirt track with no super shoes. Let's get down to racing.

@RobertMSterling @Camp4 I’m fairly fit and this dude ran a marathon at my sprinting pace.

@Camp4 Right?! It’s insane. A 4:34 mile is an absolute deadass sprint for all but the most fit people out there. And to do it 26x 🤯

Life is a marathon, not a sprint *pulls out calculator and divides 1:59:30 by 26.2* alright, you know what, life might be multiple things simultaneously

@CitiusMag 2:05 is good but what an odd stretch here

Was Sabastian Sawe’s world record not even the craziest marathon performance of the day?? 🤯 Vincent Mauri ran his first marathon the Glass City Marathon in Toledo, OH, this morning… and won in 2:05:54, becoming only the fourth American ever to break 2:06. The 25-year-old @NDXCTF and @SunDevilTFXC alum won by 15 MINUTES running solo on a USATF-certified course. Mauri finished his collegiate career in 2025 with PBs of 3:59.05 (mile), 7:50.33 (3000m), and 13:34.03 (5000m).

@MichaelDBrandt @JasonFitz1 is smiling somewhere

The only thing between you and your biggest dreams is mileage.

@zbitter 1K to go. Maybe 1200.

Sawe averaged what equates to ~105 laps around a track at ~68 seconds per lap, or 17 second 100 meters for 420 in a row without stopping. At what point in the race could you have jumped in and kept up?

@enthearena @mounttocoast It was!!

@JWLevitt @mounttocoast Amazing!!

@robertwarren @mounttocoast What an experience

@JWLevitt @mounttocoast So sick

@adamrosenfield @tckahler @deray Love it

@tckahler @deray @JWLevitt

The Maurten team took 6 trips to Kenya to work with Sawe over the past year. They developed a “personalized gut training program” for him. Nerdy details here:

@samclementt I simply cannot. I’ve barely run under 3 hours (2:59:40)

@JWLevitt Imagine running a marathon in under 2 hours

Imagine breaking two hours in your first marathon and not winning 😳

@kippbodnar @thesamparr @dharmesh Would you consider @boulderthon? Located in a running paradise, has grown from 1500 to 17k runners in 5 years. Boulder is a tech hub, and founder of race is a serial entrepreneur with a $50M exit to Grubhub in 2017. He’s a 2:42 marathoner, dad, and CEO! @PhilDumontet

@thesamparr @dharmesh We do a lot in running. Normally doth NYC marathon and London.

Woah @kippbodnar and @dharmesh -- hubspot sponsored this? Tell me the next time you sponsor a running event...I wanna go!

Love that. The audience is ripe for it, especially at the majors. Smart b2b play; you see it often with the majors. Sponsors are able to get bibs for key customers. That + marathoners skew millennial, high HHI, decision makers in HH + work. It’s why I’ve built a network for non endemics to reach new audiences! open.substack.com/pub/longrunlab…

@zbitter @CitiusMag 😂😂

@JWLevitt @CitiusMag As Tim would put it, pharmaceutical levels of carb intake. Lol

“Today, I took two slices of bread, honey and tea.” 🥖 🍯 🫖 Sabastian Sawe revealed what he had for breakfast before breaking the marathon world record in 1:59:30 at the London Marathon. 🎥 Full post-race press conference available to watch on The CITIUS MAG YouTube channel.

You have to believe that you are nowhere near your true potential.

@JBrooks77 @mounttocoast deal! i'm hoping it becomes a regular thing for mount to coast at boston. i'd love to do the double next year. gotta run my way in.

@JWLevitt @mounttocoast If you do this again count me in
