Most athletes are chasing a number that was never meant to be a target. Dr. Alan McCubbin breaks down where 90g per hour came from, why it doesn't apply to everyone, and what the research says about going higher.

As Scott puts it: there are athletes who benefit from going over 90g an hour—they feel better in the session, better after it, recover faster, sleep better, and have less muscle soreness. Until there's proof otherwise, if your power output warrants it, higher carbs are worth exploring.

Earlier this summer, Mark Stovall clocked a 12:31 at Ironman Canada, taking an hour+ off his previous best time and 30 minutes off his bike split...at 65 years of age! How did he do it? Through fueling of course. 😉

In all seriousness, Mark worked closely with our own Scott Tindal to lose weight by tracking his food, carb load in a way that met his body's needs, and fuel his races with precision. Another highlight for Mark was qualifying for the Ironman 70.3 World Championship at the Gulf Coast, where he had one of my best races ever.

There's a moment that hits a lot of athletes the week before a destination championship. Everything that was under control at home suddenly isn't. The kitchen you relied on is gone. The brands you trust aren't on the shelf. Meal timing collides with flights, jet lag, and a city on a whole different schedule.

None of that shows up in a training log. But it's often the difference between a race that reflects your fitness and one that falls short of it.

That's the thread we're following all the way to Nice, and beyond to Kona. Megan, our staff dietitian, is racing the Ironman 70.3 World Championship herself, and she'll take you through how she prepares, travels, and fuels for it in real time.

If you’ve ever slammed a caffeine gel in the last hour of a race hoping for a boost, this episode is for you. ☕️

Dr. Lindsay Hunt from Precision Fuel and Hydration joins Scott to break down the science of caffeine timing across every endurance distance (from marathons to ultras) and why the timing matters just as much as the dose.

Magda trains 20 to 30 hours a week. For a long time, she thought her hard sessions meant she wasn't good enough.

It turned out her body just didn't have what it needed to do the work she was asking of it.

“Burnout” gets thrown around loosely, but mislabeling it leads athletes to do exactly the wrong thing.

The leading framework in sport psychology is Raedeke and Smith's three-dimensional model, which defines burnout as exhaustion that rest doesn't fix, a sense that nothing feels like progress, and a growing detachment from the sport you love.

Fueling won't cure burnout, but chronic under-fueling deepens the exhaustion and drains your reserves.

Swipe through for the full picture, and be gentle with yourself about which one you're in.

Everyone's adding sled work. buying sandbags, and lifting heavier because HYROX is all about strength, right?

Wrong. Dr. Dan Plews of Endurox and Endure IQ holds a Kona age-group record and a HYROX pro doubles world record. His take is that the people who fade at station six aren't dealing with a weakness problem, but something else entirely.

They're facing an aerobic deficit, not a strength one.

Fall 2024, Tucson. One trip on a run, and Jennifer tore all 3 hamstrings off her sit bone with over 2.5 cm of retraction. Surgeons drilled into the bone to reattach them, and then came 6 weeks of bedrest and months of PT.

Here's what she figured out on that couch: her body didn't need race fuel anymore. As she put it, "My body no longer needed to be fueled for performance. It needed to be fueled for healing." So she went back to basics. More whole foods, more protein, fewer mindless snacks. She used FUELIN to reset her ranges and match her fuel to recovery instead of workouts.

Her motto through the whole thing: fuel for the season you're in. And when it was finally time to train again, she wasn't just rebuilding fitness. She was building on a much stronger nutritional foundation. In June 2026, she won her age group at Rockford 70.3. 🏆 She's got the USA Triathlon Nationals and IRONMAN 70.3 Michigan still ahead this season.

There's a strange pride a lot of endurance athletes take in flirting with overtraining, as if burning yourself to the ground proves your commitment. It's worth knowing what the science actually says before wearing that as a badge.

The European College of Sport Science laid out the accepted framework in a 2013 consensus statement (Meeusen and colleagues): a progression rather than a single event, running from functional overreaching (a normal, useful part of hard training) through nonfunctional overreaching and finally into overtraining syndrome. The further down that path you go, the longer the road back. Functional overreaching resolves in days. Full overtraining syndrome can suppress performance for months and has ended seasons.

What makes it tricky is that researchers stress the condition is multifactorial. It isn't simply "too much training." It's training stress, life stress, poor sleep, and inadequate fueling all landing at once, which is why two athletes on the identical program can have completely different outcomes.

The encouraging part: the earlier stages are recoverable and largely preventable, and fueling and recovery are two of the biggest levers you control.

Swipe through for how to spot the line before you cross it. And share this with the most disciplined person you train with.

They're often the ones most at risk.
