Coming Q4 2026  ·  Seeking Pilot Swimmers
SwimFueled™  ·  Personalized Meet Fueling Plans
Fueled
to Be
Fast.

SwimFueled builds personalized performance fueling plans for competitive swimmers — prescribed around each swimmer's body weight, events, and the exact timeline of their meet. Event by event. Gap by gap. Day by day.

400,000 Registered USA Swimming Athletes. None Have Ever Had a Real Fueling Plan.
Five pillars drive race-day performance: training, mindset, daily nutrition, recovery, and fueling. The fifth — fueling — is just as decisive as the other four, and the only one nobody has ever coached or prescribed.

SwimFueled™ is the first and only performance fueling platform built exclusively for competitive swimming — and tailored to each individual swimmer.
Something the sport has never had — is finally here.

The First Fueling Plan Built for Swim Meets.

Nutrition apps manage daily diet and macros. SwimFueled does something they don't — and can't. We prescribe exactly what to eat and drink in a 20-minute, 60-minute, 90-minute, sometimes 2-hour gap between races — at 1 to 4 day meets. Sports dietitians rarely work in this space. The science behind our protocols is peer-reviewed and well-established. We're the first to apply it to competitive swimming. That's the white space we own.

The Problem

Fueling Is
Never Coached.

01
The Unfueled Practice

School lunch at noon. Practice at 3–5 PM. A 3 to 5 hour gap — and whatever was convenient on the drive over. The problem isn't always that nothing was consumed. It's that the wrong thing was. The final high-intensity block of every practice — where races are won and lost — is run on glycogen reserves that are already gone.

02
The Meet as a Multi-Day Endurance Event

4–6 events per day. 3–5 consecutive days. Every gap between events has a different fueling requirement determined by its length. The cumulative physiological cost compounds. Not a single product has ever understood this structure — until now.

03
Why Every Day Gets Worse

Glycogen resynthesis rates are highest in the first 0–2 hours after the last race. Team dinner arrives 90–180 minutes later. Day 2 starts already compromised. Then Day 3. Then Day 4 — often when the athlete's most important event is scheduled. Swimmers adding time on Day 4 is accepted as normal. It is not normal.

"The 15-year-old showing up to Junior Nationals hoping to achieve best times while college coaches are watching from the stands is trained to perform — but without proper fueling over a 4-day meet, the result is left to chance. I want every swimmer to show up to meets not only swim trained, but also swim fueled."

The Five Pillars of Race-Day Performance

Four Pillars Are Coached.
Fueling Never Has Been.

01
Training & Technique
The work in the pool.
Coach's domain
02
Mental Readiness
Focus, nerves, and race-day mindset.
Swimmer & sports psychologist
03
Daily Nutrition
The everyday diet that keeps a swimmer healthy and growing. SwimFueled provides carb & protein targets and food guidance — but meals are not prescribed.
Swimmer & nutritionist/dietitian
04
Recovery
Sleep and rest, where training becomes fitness.
Swimmer's domain
05
Fueling
The right fuel, in the right amount, at the right time — prescribed around every practice and every race.
SwimFueled's domain
The one nobody has ever coached or prescribed. Until now.
The Solution

A Specific Prescription.
Not Generic Advice.

What to eat, how much, when, and which products — calculated from each swimmer's body weight, event schedule, and tested food tolerances. Built around food the swimmer already eats. Not a diet. Not a bottle of supplements.

Deliverable 01
Training Fueling Plan

A weekly fueling plan tailored to each swimmer's individual practice schedule — prescribing exactly what to eat before, during, and after every session, including double-practice days. Nothing is left to guesswork.

→ Personalized to body weight and training load
→ Single and double sessions covered
→ Carb & protein targets included
→ Takes the fueling conversation off the coach's plate
Deliverable 02
Meet-Day Fueling Protocol

A complete, event-by-event fueling plan from waking up on Day 1 through the last cool-down of the meet. Every gap between events is calculated. Every day is covered. Built from the actual psych sheet.

→ Gap-aware — 20 min, 60 min, 2 hours all handled differently
→ Day-by-day, event-by-event prescription
→ Shopping list included
→ Nothing new on race day

The Team

Built by People Who Lived It.

SwimFueled was not built by people who read about the problem. It was built by people who lived it — as athletes, as coaches, and as the swimmer the product was made for.

Dora Jih
Dora Jih
Founder & CEO
Cornell ORIE B.S. + M.S. Cornell MBA 16× Ironman Ironman World Championship 2022 Triathlon Coach Since 2018

First triathlon 2004. First Ironman 2007. Racing Ironmans every year from 2010 — Ironman World Championship 2022, 16th Ironman Lake Placid 2024. Triathlon coach since 2018. In the 2024 season, coached five athletes including herself — all five qualified for the Ironman World Championship, three won their age group.

Watched Ana, her daughter, live the fueling gap at every level of competitive swimming from 2015 through UCLA graduation in 2025. Spent nearly a decade knowing exactly what product needed to exist. Now has the team, the story, the technology, and the proven methodology to build it.

Triathlon racing and coaching gave her the lens to recognize the problem and the conviction that a system could solve it. SwimFueled is something entirely new — built for a competition structure that has no equivalent in endurance sport.

Ava Jih-Schiff
Founding Engineer
Stanford B.S. EE Stanford M.S. CS ASIC Engineer · Nvidia Stanford Artistic Swimming · Collegiate National Champion Ironman World Championship 2025

4-year Stanford Artistic Swimming Team member and Collegiate National Champion. Coached by Dora in triathlon. At her first triathlon — a 70.3 in Santa Cruz, CA — qualified for the Ironman 70.3 World Championship. At her first full Ironman — Ironman California 2024 — won her age group and qualified for the Ironman World Championship, finishing with specific carbohydrate targets for each segment and a fueling strategy tested in training. Obtained a Boston Marathon qualifying time at her first marathon, finishing in 3:22. In every instance, Ava followed a prescribed fueling plan without fail.

She is not just SwimFueled's engineer. She is living proof that the methodology works at the highest level on the first attempt — across three different disciplines, three times. Leads all technical development.

Ana Jih-Schiff
Co-Founder, Brand & Growth
UCLA D1 Swimmer NCAA Qualifier 3× School Record Holder UCLA Female Scholar-Athlete of the Year 2025

Competitive swimmer from age 5 through NCAA Championships. Made A Finals at Big 10 Championships. Qualified for NCAA Championships — 3 individual events + 4 relays. Graduated UCLA June 2025 with the highest GPA of any female athlete across all sports in the graduating class. Completed the 2025 LA Marathon in 3:27 in her first marathon — with a fueling plan.

Psychology major at UCLA, Ana understands that the mental component of racing — confidence, focus, the belief that you've done everything right — is inseparable from physical preparation. A swimmer who shows up properly fueled doesn't just perform better. She competes differently.

The product is built for who she was, the performance she knew was possible, and the thousands of swimmers who are exactly where she was before she figured it out.

She speaks the language because she lived it. She can walk into any pool deck in the country and every swimmer, parent, and coach in the room immediately understands why she built this.

"This is not a brand looking for a face. This is a product built by athletes who lived the problem, proved the solution in their own performance, and refused to let another generation of swimmers show up to their most important race with a granola bar and a Gatorade."
