Race season ramps up training demand fast. But if your nutrition hasn't kept pace, your body will start sending signals.

Persistent fatigue, slow recovery, recurring niggles, mood drops, performance plateaus. These aren't just "part of the grind." They're signs your fuel isn't matching your workload. 😴

Swipe through and check yourself honestly. If any of these land, your fueling deserves a closer look.

Boston. Is. Coming.

And it starts tight, loud, and downhill. The worst thing you can do? Get anxious.

The moment you start weaving, surging, and lengthening your stride to find space, you're writing checks your quads will cash at mile 20.

Stay calm. Light feet. Quick turnover.

Join us for a full Boston course preview with V.02's Brian Rosetti. Link in comments.

It doesn't get more brutal than this.

Paris-Roubaix is the race where fueling strategy can be the difference between the velodrome and the side of the road.

More work, more carbs. Always.

Happy Sunday, cycling fans. 🚲

Race season and aggressive calorie restriction are a difficult combination, and it's one of the most common performance mistakes endurance athletes make. Not because the goal is wrong, but because the timing is.

Low energy availability in this phase actively works against what matters most right now: high-intensity output, glycogen restoration, recovery between sessions, and the hormonal environment that drives adaptation.

The athletes who arrive at race season leaner and faster got there through precision: fueling hard days hard, scaling back on easy days, and letting the training load do the work over time.

That's performance-first nutrition. And it's exactly what Fuelin is built around.

→ Save this. Worth revisiting the next time restriction feels like the answer.

Olympic gold medalist. Kona champion. Showed up to the Paris Half Marathon undertrained, with no real carb load the night before. Still ran 1:11.

In this episode of the Fuelin Sessions, Jan Frodeno breaks down his exact race day fueling protocol: Maurten bicarb, caffeine timing, gel frequency. He lets us in on what it reveals about the difference between a fueling strategy and a fueling panic. (Hint: direction beats perfection.)

We want to hand it to Laura Sheridan for her performance at last month's Howard Aslinger 12-hour ultra run. 🏃🏻 🎉

Laura came first overall and ran 76.23 miles in 12 hours.

We helped with the carbs, sodium, and strategy, but Laura brought the grit. Congrats!

Fuelin-approved uses for your household Easter candy haul:

Jelly beans: shove a handful in your pocket before your long run. Legitimately great race fuel.

Hot cross bun: pre-ride breakfast. 55g carbs. Toast it. Butter it. Go ride.

Mini Eggs: pre-workout snack. Eat them in the car on the way to the track.

Creme Egg: hand it to your training partner at the halfway point. Hero move.

Hollow chocolate bunny: night-before-long-run carb load. Obviously.

Reese's PB Egg: eat it on the couch. This one's just for you.

Peeps: ...slowly relocate to the garbage. We're nutrition experts, not miracle workers.

Happy Easter. May your glycogen be full and your race season be long.

A pro triathlete slammed 8 gels at once mid-race and won.

So what actually happened?

Scott and Jan unpack the science behind why Trevor Foley's Hail Mary at Ironman New Zealand worked: hydrogel clearance, insulin response during exercise, and why your gut behaves completely differently when you're moving. (And why you should always build your race day fueling strategy progressively with Fuelin.)

It's one of the wildest race nutrition stories we've heard, and the biology behind it is genuinely fascinating. Full episode out now. 👇

We owe you an honest conversation.

After years of telling you to eat more carbs, match your fuel to your training load, and trust the science, we went back to the research.

And we have an update.

We know this might surprise some of you. Watch the full announcement from Scott above. 🥑
