Before we talk about nutrition theory or training plans, let’s start with the only thing athletes truly care about: results. In a single season, Sarah Gable — a 46-year-old nurse, mother of three, and late-in-life runner based in Iowa - took almost 15 minutes off her half-marathon time, dropping from 3:26 to 3:12 in just four months. More importantly, she did it without burning out, breaking down, or letting training take over her life. There was no new coach. There was no radical training block. There was no overnight transformation. Just one fundamental shift: she stopped under-fueling training and started eating for the work she was doing.
A Familiar Pattern, Until Running Entered the Picture
Sarah didn’t grow up as “the athletic kid.” Like many women, she learned early that staying on top of food meant control, tracking, and discipline. Over the years she cycled through systems that promised structure: Weight Watchers, manual calorie tracking, Noom. They worked - until she started training. Once running became part of her life, the cracks appeared. Long runs left her starving. Recovery lagged. Energy dipped on workdays and night shifts. Still, the guidance stayed the same: cap intake around 1,500–1,600 calories, even on run days. She wasn’t failing the plans. The plans weren’t designed for an athlete. This is a common reality for anyone who uses a macro tracker. They work until they don't work!
Structure Without Restriction
Sarah discovered Fuelin mid-season, between her first and second half marathon. Not as a diet. Not as a weight-loss tool. But as a framework to finally align food with training. The numbers felt aggressive at first. “I thought I was eating enough protein,” she says. “I wasn’t even close.” Instead of negotiating with hunger, she planned for it. Instead of earning food, she fueled her training correctly.
- Around 2,000 calories on rest days
- Up to 2,600 calories and 250 grams of carbohydrates on long-run days
- 180 grams of protein daily, up from roughly 100

When Fueling Matches Training, Training Starts Working
The shift showed up quickly. Runs stopped feeling like survival events. Strength sessions didn’t sabotage recovery. She could stack days instead of bouncing between “big weeks” and forced downtime. Hunger — especially at night — eased. Energy stabilized. Training became repeatable. And then the performance followed. Her second half marathon came in 15 minutes faster. Not because she trained harder, but because the training finally counted.
The Part Most Athletes Don’t Want to Hear
During peak training, Sarah gained about 10 pounds while fueling properly. That wasn’t failure. It was feedback. After the race, she adjusted her targets and her weight normalized — without sacrificing energy, consistency, or performance. This is the distinction most athletes never make: Fueling for training and managing body composition are different phases. Treating them as the same thing is how progress stalls.
Lessons That Apply to Almost Everyone
Sarah isn’t an elite athlete. She’s not chasing podiums. She’s chasing health, longevity, and progress that fits into a real life. Her story reinforces a few truths that apply broadly: 1. Hunger during training is information, not weakness. 2. Protein needs are higher than most athletes think, especially when lifting and running. 3. Training plans prescribe work — they don’t support it. 4. Consistency beats heroic workouts every time.
Why This Story Matters
Because Sarah didn’t reinvent herself. She didn’t unlock hidden talent. She simply stopped fighting her physiology and gave her body enough fuel to adapt to the work she was already doing. Her season is proof that many athletes aren’t undertrained. They’re underfueled. Sometimes the breakthrough isn’t another workout. It’s finally eating for the one you’re already doing.
