Pick the AssaultRunner Pro for interval training, a full console, and easier availability. Pick the Trueform Runner for stride feel, walking comfort on a curve, and maximum capacity. Neither is better in the abstract; they are tuned to different nervous systems.
Curve personality
The Assault curve spins up eagerly and suits athletes who change pace constantly. The Trueform curve is shallower and steadier, suiting form work and longer, calmer efforts. Most cross-shoppers who try both choose within ten minutes, on feel alone.
Data versus purity
The Pro ships with interval programming and wireless heart rate links. The Runner ships with a basic display and sells its experience as the absence of distraction. Coaches who program from the console prefer the Pro; coaches who program from a stopwatch prefer the Trueform.
