SUPLiR App
Read full descriptionHide full description
You bonked at km 80. Not because you trained badly — because you guessed. SUPLiR keeps an inventory of the gels, bars, drink mixes and chews you actually own, then turns a planned session into a timed fuelling plan built from that stock. Grams of carbohydrate per hour, item by item, with hydration, sodium and caffeine ceilings respected. Describe the session in a sentence — "4h endurance ride, warm, two climbs" — and the plan is there. WHAT IT DOES - Timed fuelling plans from your own products, not a generic table - Carb loading across the three days before an event, 8–10 g/kg - A phased 48-hour recovery protocol - Caffeine timed 45–60 minutes before peak effort, inside your daily limit - Import from Strava, Komoot, Garmin Connect, .ZWO, .GPX and .FIT - Built on your numbers: weight, FTP, VO2max, carb ceiling FOR Cyclists and runners training six to twelve hours a week, racing two to four times a year, who want the fuelling to be as considered as the training. SUPLiR is a planning tool, not medical advice. Consult a professional for individual nutritional guidance.
