Running is for marathoners, fitness enthusiasts and ironman competitors. Roadwork is for boxers. Traditional roadwork shouldn’t necessarily be approached the same way. Instead it should be exactly what it says, work on the road.
The goal of your roadwork routine, just like it is with every other aspect of your training, should be for it to apply specifically to boxing. This means, among other things, that it must incorporate variety. Like the characteristics of a boxing match it should include, bursts of action, moments of lesser activity, lateral movement, forward and backward motion and periods of heightened resistance. Each component has its place in the ring, so it should also have its place in your roadwork training.
