Reference times, trainer baseline, whole-life economics. Your own time changes the answer — use the reading above.
The softest ride at this level by some distance, and the third generation finally made it serious rather than just fun. A genuine top-tier option.
■ Caution IncrediRUN is extremely soft. If you like a firm, connected racer this will feel vague underfoot.
The best value at the very top of the market. Within touching distance of the Evo 2 for performance at half the price and twice the life.
■ Caution The EnergyRods give a distinctive rolling feel that some runners never get on with. Try before you commit if you can.
