Can you build a decent level of fitness during off season training to transition to ultra by running as little as 3 times a week on 30 miles per week? I was thinking 5 miles + 10 miles + 15 miles each week.
I've done a 3 marathons. During my off seasons I run 5 times a week around 20 to 25 miles per week. I'm thinking about moving into ultra world and am also exploring if there is a way to train smarter so I don't run as many days. Does a 'less is more' approach work? I've read how some people do run less days and focus on 'quality' runs with more recovery in between.
Obviously when (if) I decide to register for an ultra event I would of course gear up by following a proper program which would no doubt involve more running.
Grateful for your views
