PaceRun+: The ultimate running calculator for ultra-realistic race predictions. Preparing for a race, a trail, or a long run? Don't settle for a constant theoretical pace. PaceRun+ is the innovative running app that adjusts your split times based on terrain reality and human physiology. WHY CHOOSE PACERUN+? Most standard running calculators assume you run at a perfectly linear speed. PaceRun+ breaks this rule by integrating critical parameters that impact your actual performance: elevation gain, muscle fatigue, and energy needs. KEY FEATURES: • ACCURATE RUNNING CALCULATOR: Instantly calculate your pace, speed, or finish time for any distance (5k, 10k, Half, Marathon, and custom distances). • ELEVATION CONVERTER (GAIN): Don't be surprised by the terrain. The app uses the "Grade Adjusted Pace" rule (100m of elevation gain = 1km of additional effort) to provide a pace adjusted to the actual difficulty of the course. • FATIGUE MANAGEMENT: Be realistic with your goals. Set a cardiac drift or fatigue coefficient starting from the kilometer of your choice to anticipate the end of the race. The app recalculates your splits to reflect your progressive slowdown. • SMART NUTRITION PLAN: Manage your carbohydrate strategy (g/h) to optimize your performance. PaceRun+ calculates the total required and places visual refueling reminders (gels, drinks) directly into your pace chart. • DETAILED SPLITS TABLE: Get a complete kilometer-by-kilometer (or mile-by-mile) roadmap. Visualize your specific pace, elapsed time, and fueling moments for perfect race day management. FOR ALL RUNNERS: Whether you are a road runner chasing a PB or a trail runner preparing for a hilly race, PaceRun+ is the essential planning tool. Instantly toggle between Kilometers and Miles based on your needs. Move from theory to reality. Optimize every stride, master your pace, and plan your performance with PaceRun+.
