How often do you run 5 miles straight in rugby?
HIIT is your best bet (it is generally everyone's best bet, my buddy once told me the only person he'd prescribe steady state cardio for is a morbidly obese person whose joints would be completely fucked by steady state cardio, so no one.).
If you don't know what HIIT is, I'm sure someone else will post or you can google it.
this, throw some hills in there too
in sports like rugby ur explosiveness will help ALOT, maybe work on that not just endurance
