This distance, this body, this weather — what fuel?
The questions runners paste into race groups, answered from the verified database with the same engine as the finder, plus the part a table cannot tell you: why, and what goes wrong. Every answer opens the finder with your profile filled in.
Best fuel for a hot marathon with a sensitive stomach
Heat and a touchy gut pull in opposite directions: you need more sodium and more fluid, but every extra thing you swallow is a risk.
What to eat during your first half marathon
Two hours or under. You need less than you think, and the thing that goes wrong is usually taking something new on race morning.
A caffeine plan for a sub-3 marathon
Caffeine works, but the dose and the timing matter more than the brand, and stacking caffeinated gels is how people end up jittery at mile 10 and flat at mile 22.
Fueling a 50-miler when gels stop working
Somewhere around hour six sweet gels become impossible. The answer is a rotation — savory, real food, drink — not a better gel.
Vegan fuels that can hit 90 g of carbs an hour
Almost every serious race fuel is already plant-based; the question is which ones deliver the density and the 2:1 blend a trained gut needs.
Fueling a cool marathon as a heavy, salty sweater
Cool weather does not switch off a high sweat rate. If your kit is white with salt after a long run, sodium still belongs in the plan.
Gels you can take without water
Isotonic and liquid gels are built to go down on their own; a thick gel taken dry sits in the stomach until water arrives.
The cheapest way to fuel a marathon properly
Hitting 60–75 g/hr for four hours can cost $8 or $40 depending on the product. The cheap answer is usually a drink mix plus a supermarket carb.
