Triathlon Fueling: How to Eat and Drink Across Swim, Bike and Run Without Bonking
Triathlon fueling is uniquely tricky — you’re eating and drinking across three disciplines with different demands, and getting it wrong means bonking or a rebelling stomach mid-race. The tri guide: why fueling is complex, the by-discipline plan and the practice-it notes. (Not medical advice.)

The Fueling-Is-Complex Case
Why triathlon fueling is tricky: the three-disciplines-different-demands (the swim, bike and run having different fueling-demands from the triathlon-training-plan-sprint chapter — the the-three-disciplines; the different-demands), the getting-it-wrong-bonks-you (the poor fueling causing bonking from the first-triathlon-guide-women chapter — the the-bonk; the bonk-risk), the the-stomach-can-rebel (the wrong-fuel upsetting the stomach mid-race from the first-triathlon-guide-women chapter — the the-gi; the stomach-rebels), the the-bike-is-the-fueling-window (the the-bike being the main fueling-opportunity from the triathlon-brick-workouts chapter — the the-bike-window; the fuel-on-the-bike), and the reframe (the triathlon-fueling as a complex, three-discipline, bonk-and-GI-risk challenge with the-bike-as-the-window).

The By-Discipline Plan
The fueling plan by discipline: the the-pre-race-fuel (the a-pre-race breakfast-and-fuel from the first-triathlon-guide-women chapter — the the-pre-race; the fuel-before), the the-swim-no-fueling (the no-fueling during the swim (fuel before) from the open-water-race-swim-survival chapter — the the-swim; the fuel-before-swim), the the-bike-is-the-main-window (the fueling on the bike (gels, drinks) from the triathlon-brick-workouts chapter — the the-bike; the fuel-on-bike), the the-run-easy-fuel (the easy fuel-and-hydration on the run from the triathlon-training-plan-sprint chapter — the the-run; the run-fuel), the the-hydration-throughout (the hydration across the race from the first-triathlon-guide-women chapter — the the-hydration; the hydrate), the the-electrolytes (the electrolytes for longer-races from the first-triathlon-guide-women chapter — the the-electrolytes; the electrolytes), the the-transition-fueling (the grabbing fuel in transitions from the triathlon-transition-practice chapter — the the-transitions; the fuel-in-transitions), and the the-by-distance (the fueling scaled to sprint-vs-longer from the triathlon-training-plan-sprint chapter — the the-distance; the by-distance).
The Practice-It Notes
Practicing your fueling: the the-practice-in-training (the testing fueling in brick-workouts from the triathlon-brick-workouts chapter — the the-practice; the test-it), the the-nothing-new-on-race-day (the no-new-fuel on race-day from the first-triathlon-guide-women chapter — the the-rule; the nothing-new), the the-find-what-your-stomach-tolerates (the finding tolerable fuel from the first-triathlon-guide-women chapter — the the-tolerance; the what-works), the the-practice-transitions (the practicing transition-fueling from the triathlon-transition-practice chapter — the the-transitions; the practice-transitions), the the-hydration-strategy (the a-practiced hydration-plan from the first-triathlon-guide-women chapter — the the-hydration; the plan-it), the the-budget-gear-and-fuel (the budget fuel-and-gear from the triathlon-gear-budget chapter — the the-budget; the affordable), the the-individual-plan (the fueling being individual from the triathlon-training-plan-sprint chapter — the the-individual; the your-plan), and the frame (triathlon-fueling as pre-race-swim-before, bike-window-and-run-easy, practiced-with-nothing-new-on-race-day — eat and drink without bonking. Fuel a triathlon by discipline — fuel before (and before the swim), use the bike as your main fueling window (gels, drinks), take easy fuel-and-hydration on the run, and grab fuel in transitions — all practiced in brick workouts (nothing new on race day, finding what your stomach tolerates): how to eat and drink across swim, bike and run without bonking.
Triathlon fueling is uniquely tricky — you’re eating and drinking across three disciplines with different demands, and getting it wrong means bonking or a rebelling stomach. The by-discipline plan: fuel before (and before the swim, since you can’t fuel during it), use the BIKE as your main fueling window (gels, drinks), take easy fuel-and-hydration on the run, hydrate throughout with electrolytes, and grab fuel in transitions (scaled to distance). Practice it — test your fueling in brick workouts, do nothing new on race day, find what your stomach tolerates, and practice transitions.
