This is one of the best trainer for any distance starting 5k to Full marathon. It has great cushion and yet it's propulsive enough for the speed workouts. Ideal for long runs, tempo runs, intervals and even racing, why not? I wouldn't recommend people to use this for daily use or walking.
Q:What is better option for marathon?? Asics Nova blast 4 or this one?
A:Novablast 4 works well as a daily trainer, while the Endorphin Speed 3 is better for speed work and racing. If choosing one, the Endorphin Speed 3 is a more versatile option.
