The main difficulty with that is that my 80/20 plan ranges from 4-7.75 hours/week. 80 percent of that is 3-6.2 hours/week. Even if I take the shortest path to and from work every day, that still puts me running more like 8 hours a week just for my commuting.
The shortest route I can take is a hair under 8 kilometers. Over the last 6 months or so, I’ve been pretty much exclusively running (biking in the winter is not super fun for my hands), and I’ve been working up to longer and longer distances. For the last two months or so, I’ve tended to take a route to work anywhere from 10 to 15 kilometers, and a route home that’s a bit shorter than whatever I ran that morning. I carry a backpack in the 4-5 kilo range. I’m almost embarrassingly slow; my pace hovers around 6 minutes per kilometer, which is why I want to give 80/20 a shot. So my run to work could be as short as 48-50 minutes, but lately has been as long as 90.
