Plan9

I run sometimes. I used to get paid to run kinda far carrying heavy backpacks.

When I started running I couldn't do a quarter mile without huffing and puffing and dying.

Couple years back I did a ten miler well under 80 minutes. Probably my best time ever.

My perpetual To Do since 2007 has been to train up for and run a marathon but life has made it difficult.

That and I'm lazy.

Don't focus on speed, focus on endurance. Just set distance goals and get there.

You'll build up to it as long as you consistently train. Stick to it. Every other day was best for me.

Once you get reasonable distances down, such as 4 miles, you can do sprints.

Run a mile, sprint for 30 seconds, run a mile, sprint for 30 seconds, etc.

Sprints really improved my game because they get the muscle outta monotony.
