Hey everyone 👋 After 10+ years of running ultras, experimenting with fueling strategies, and mixing spreadsheets with sports science — I finally built the tool I always wanted: Ultra Nutrition Calculator 🏃‍♂️💥 It helps endurance and ultra runners plan their race nutrition — carbs, electrolytes, and hydration — based on their body, race duration, and terrain. No more guessing, bonking, or overcomplicating fuel plans. Just data-driven fueling you can trust for long-distance events. I’d love your feedback — whether you’re a runner, triathlete, coach, or just curious about endurance tools. 🔥 What features would you find most useful? 🔥 Any integrations you’d like to see next (Strava, TrainingPeaks, Garmin)? Thanks for checking it out and supporting a passion project years in the making 🙏 Let’s make endurance fueling smarter — and a lot more fun! — Krasen 🏔️ https://ultranutritioncalculator...
