Runtools Calc vs Aero Endure

RunTools Calc is a free training calculator built for runners and coaches who care about accuracy. Most running apps overcomplicate simple math. RunTools Calc focuses on what actually matters: splits, pace, and performance clarity—presented in a clean, readable format. Features • Calculate splits for any distance and total time • View pace in min/mi, min/km, mph, and km/h • Simple vertical split layout designed for quick reference • Accurate pace formatting (no broken times like 3:60) • Preset distances including Mile, 8K, 10 Mile, 15K, Half Marathon, and Marathon • VO₂ calculator with fitness-level insight • Built for athletes, coaches, and serious training Whether you’re planning workouts, checking race pace, or coaching athletes, RunTools Calc gives you the numbers you need—without noise. Train smarter. Run with precision.

Aero is two apps in one: a clean running tracker for athletes, and a complete coaching platform for the people who train them. FOR RUNNERS • Log every run — distance, pace, time, and route — and watch your fitness build. • Keep your streak alive. Aero tracks your consistency so showing up becomes a habit. • A community feed built for runners: share runs, cheer teammates, and follow the athletes who push you. • See your trends. Weekly mileage, pace progression, and personal bests, explained in plain language. • Connect what you already use — sync runs automatically so nothing gets lost. FOR COACHES • Manage your whole roster from one command center — every athlete, every run. • Assign workouts and build training calendars your athletes see instantly. • Spot who's improving and who needs attention with at-a-glance team analytics. • Organize athletes into teams and groups, and invite them with a single code. • Flexible plans that scale with your roster, from a handful of athletes to your entire program. WHY AERO Most run trackers stop at the individual. Most coaching tools ignore the athlete experience. Aero connects both sides — so the run an athlete logs this morning is the data their coach acts on this afternoon. Start free as an athlete.
