Tired of hitting the wall in the half, the marathon, or an ultra? CarbRate builds you an individualized fueling plan for your race. It tells you exactly how much, when, and what to eat and drink, to maximize your race day performance. Your fueling plan is built around your goal time, how fast your body burns glycogen, your measured sweat rate, your actual course, the gels and drinks you prefer, and the weather on race day. You also get detailed practice instructions to train your gut before the race. And on race day, CarbRate guides you through the plan live, so you don't have to remember any of it. BUILT FOR YOUR EXACT COURSE Pick your race and CarbRate builds your plan around its hills and aid stations. It places every gel and drink where there's water to wash it down, and times any caffeine you take to peak in the hardest miles. If your race isn't listed, CarbRate builds your plan from your distance and goal time instead. PERSONALIZED TO YOUR BODY AND GOAL Your weight, goal time, and sweat rate change how much fuel you need, and your stomach changes how much you can take in. A guided sweat test, a weigh-in before and after a normal run, turns sweat rate from a guess into a measured number. Log your runs and they teach CarbRate what your stomach handles, so your fuel targets rise as your gut adapts. READY FOR RACE-DAY WEATHER On a hot day, CarbRate shifts carbs from gels into your drink, so you take in fluid and fuel together and your stomach stays settled. Whatever the forecast does before race day, CarbRate updates your plan to match. LIVE GUIDANCE THROUGH EVERY GEL AND DRINK On race day, a calm voice prompt from your phone announces each gel and drink before it's due. The screen stays in your pocket, and the plan does the thinking for you. TRAIN YOUR GUT TO HANDLE MORE FUEL Your stomach can learn to absorb more carbs per hour, and that extra fuel is what keeps your pace from fading in the last miles. CarbRate turns your long runs into fueling rehearsals, and you log how each one went. Then it tells you the one change to make next time: push to 80 grams an hour, take your first gel earlier, or swap the gel that upset your stomach. USE THE PRODUCTS YOU ALREADY LIKE Your plan is built from the fuel you already train with: more than 160 gels, chews, and drink mixes with verified carb counts. If your favorite isn't listed, add your own. KNOW WHY YOUR PLAN WORKS An 8-module course explains your plan, covering hydration, glycogen, gut training, carb loading, the taper, and which supplements are worth your money. By race day, you understand every line of your plan, and trust it in the late miles. WHAT'S FREE Answer a few quick questions and get a real plan: your carb and fluid targets for the whole race, a chart of your fuel level mile by mile, and the first hour of your race-day schedule. You also get the first course lesson, one guided sweat test, a race countdown with daily fueling tips, and you can add your own products. The free version never expires. WHAT PRO ADDS Your complete race-day schedule, from the first gel to the finish line. The full fueling course. Unlimited sweat tests. Tracking for every practice run, with feedback on what to change next. A carb-loading plan for the final days before your race. And live voice guidance on race day itself.
