What this server can do
7 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
carb-loading(raceType, experience, hasGIIssues, bodyWeightLbs, finishTimeHours, finishTimeMinutes)- Calculate pre-race carb loading targets by race type, body weight, finish time, and experience level. Returns daily carb target, protocol length, total carbs, and pre-race meal size. Required: bodyWeightLbs, raceType, finishTimeHours, finishTimeMinutes, experience.
fueling-plan(hours, buffer, gelKey, minutes, drinkMix, intensity, targetCPH, experience, drinkCarbsTotal)- Build a minute-by-minute race or long-run fueling plan. Returns target carbs/hour, gel count, gel timing schedule, and total carbs. This is the core FuelCenter tool. Required: hours, minutes, intensity, gelKey.
gel-comparison(sortKey, sortDirection)- Return the FuelCenter gel catalog (SiS Beta Fuel, Maurten, Precision, GU, Tailwind, Spring, Carbs Fuel, neversecond, Huma) with carbs, price, caffeine, weight, and carbs-per-dollar. Optionally sort.
heat-adjustment(tempF, humidity, distanceMiles, paceSecondsPerMile)- Estimate how temperature and humidity will slow your race pace and change your fluid needs. Returns adjusted pace, slowdown percent, dew point, risk level, and fueling note. Required: paceSecondsPerMile, distanceMiles, tempF, humidity.
hydration(tempF, humidity, intensity, bodyWeightLbs, durationMinutes)- Estimate fluid and sodium needs for a race or long run based on body weight, duration, intensity, temperature, and humidity. Required: bodyWeightLbs, durationMinutes, intensity, tempF, humidity.
pace-calculator(mode, totalSeconds, distanceMiles, paceSecondsPerMile)- Given any two of distance, total time, or pace-per-mile, calculate the third. Returns pace per mile, per km, splits, and speed. Required: mode.
race-time-predictor(exponent, knownTimeSeconds, knownDistanceMiles)- Predict your finish time at common distances (5K through 100 miles) from a recent race result using the Riegel formula. Required: knownDistanceMiles, knownTimeSeconds.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
