Heavy Stride vs StepDerby

Heavy Stride is built for ruckers who want more than a generic walking workout. Track rucks on iPhone or Apple Watch with live distance, pace, calories, steps, heart rate, elevation, and pack weight. Review finished workouts with route maps, splits, break detection, load-aware recovery metrics, and analytics designed around load-bearing training instead of generic walking summaries. Heavy Stride helps you: • start workouts from phone or watch • set exact distance targets, including long events like 26.2 • track long rucks accurately on Apple Watch and iPhone • review maps, splits, and break-adjusted pace • infer stops after the workout, then edit or remove breaks and recalculate split pacing • compare training load, weekly tonnage, and same-weight pace improvement across workouts • understand how pack weight affects effort, calories, ruck work, and training stress • keep a live ruck visible across phone and watch, then transfer to iPhone if the watch battery gets low • share a polished route-and-stats recap image through Messages, Mail, and other share targets The companion experience keeps workouts visible across devices so you can train with the device that best fits the moment, hand off from watch to phone when needed, and still review the same workout afterward on iPhone.
