Eat to Endure: Dean Karnazes on Ultra Running Nutrition Without Burnout

In episode #202 @KylaChannell talks with elite row

In episode #202 @KylaChannell talks with elite rower @EllaCossill about what professional rowing actually demands, breaking down how she fuels 6,000 to 8,000 calories a day, why rowing culture pushes performance over thinness, and how she times carbs, caffeine, and bicarbonate around racing.⁠

The list of supplements with strong evidence for e

The list of supplements with strong evidence for endurance athletes is short. Six, by the Australian Institute of Sport's ranking. 💊⁠
⁠
Caffeine, creatine, nitrate, beta-alanine, sodium bicarbonate and glycerol. Even these aren't for everyone: bicarb is for short, hard efforts, beta-alanine helps 1–4 minute surges, and glycerol is a hot-race tool.⁠
⁠
Before you add anything: make sure it's third-party tested (Informed Sport or NSF Certified for Sport), try it in training, and get your daily fueling right first. No supplement fixes a fueling gap.⁠

One of you wrote: "We need us older ladies studied too!" You're right. This one's for you. 💪⁠
⁠
Only about 6% of sports science studies include only women, and far fewer look at women over 40. So here's what we know, and where we're still working it out.⁠
⁠
Protein needs go up as muscle becomes less responsive. Carbs still fuel your hard sessions, and under-fueling raises RED-S risk at any age. And bone loss speeds up through the menopause transition, so lifting, impact, calcium and vitamin D matter more than ever.⁠
⁠
Track how you respond, and adjust. That's what we do with every athlete in this stage.⁠

Two humans. No sleep. Same old fueling plan? 🍼⁠
⁠
@sarahsturmy races gravel and mountain bikes at the pro level. Right now she's in the fourth trimester. Her words on the image say it better than I can.⁠
⁠
Here's what the numbers look like.⁠
⁠
📊 Breastfeeding raises daily energy needs by about 330 calories in the first 6 months, and about 400 in months 6 to 12 (Dietary Guidelines for Americans 2020 to 2025).⁠
💧 Total water needs rise to about 3.8 liters a day while breastfeeding (IOM 2005). That counts water from food too.⁠
🚴 Those numbers are for non-athletes. Add training back in and the gap gets big, fast.⁠
⁠
⚠️ So here's the trap. You're tired. Your appetite is all over the place. You want your body back. Undereating feels like a plan. It's not. Low energy availability is linked to impaired recovery, mood, and bone health (Mountjoy et al. 2023). A new mom returning to training is right in that risk zone.⁠
⁠
✅ What we focus on with postpartum athletes:⁠
🔹 Eat on a schedule, not on hunger cues that sleep loss has scrambled⁠
🔹 Protein at every feed (yours, not just the baby's)⁠
🔹 A water bottle everywhere you nurse⁠
🔹 Fuel every ride once training comes back, even the "easy" ones⁠
🔹 Labs. Ferritin is often low after birth. Check it, don't guess.⁠
⁠
Your body just did the hardest endurance event there is. Fuel it like one.⁠

The night-before pasta party is tradition. It's also about 24 hours too late. 🍝⁠
⁠
Topping up glycogen takes roughly 36–48 hours of high-carb eating. For races over 90 minutes, that means about 10–12 g of carbs per kg of body weight per day, for the two days before.⁠
⁠
Lower fiber and lower fat makes that volume possible without feeling stuffed. And test it before a training race first.⁠

There's no single "right" number of carbs per hour

There's no single "right" number of carbs per hour. It depends on how long you're out there.⁠
⁠
Under 45 minutes, you don't need any. Between 1 and 2 hours, up to 30 g/hr. 2 to 3 hours, up to 60. Past about 2.5 hours, well-trained guts can handle up to 90 g/hr, but only with a glucose + fructose mix and practice.⁠
⁠
The mistake I see most: athletes jump straight to 90 on race day because a pro does it. Your gut needs training too. Add about 10 g/hr each week on long sessions and see how you feel.⁠
⁠
Save this for your next race plan, and send it to the friend who still races on one gel.⁠

You asked, so here's part 2. 🍌⁠
⁠
The 8–12 g/kg carb range is for athletes training 4–5 hours a day. Most of you need far less on a normal day.⁠
⁠
The window that matters most: the first 4 hours after a hard effort when you're going again within 8 hours. That's when we push about 1–1.2 g/kg of carbs every hour. Real food works. So does a smoothie.⁠
⁠
If your next hard session is 2 days away, your normal meals will get you there.⁠
