Have you tried bike riding, like with a good road bike? I find it a great deal more fun and exhilarating than running ever was.

> it is boring

It might not work for you, but for me, the joy in running comes from using that time to let my mind wander. Sometimes I use it to think about work and sometimes I just daydream. It can be a great meditative conduit.

I would suggest you to try swimming. So much fun compared to running .

You might try adjusting your pace some. If you are 100% spent after your runs you should slow down a lot and see if that helps. Alternatively, if you aren't dying at the end of your runs maybe try and run a little faster. A fun workout to do is to start slow and warm up for 1-2km then pick out a landmark that is relatively close like a telephone pole or a tree and then sprint to it. Once you get there show down to a recovery pace and pick out another landmark at which you begin sprinting again. This is called a "fartlek" it is characterized by sprints and recovery periods that are irregular distances. You are not sprinting for 400m every time.

I run for 45-60 minutes and it's perfect podcast time. (I only enjoy running on the treadmill, so earbuds are no safety hazard and I can tune out the standard exercise music in the gym.)
