What about a particularly exciting book in audiobook form?

To get back into running I listened to some page turners, but I’d only listen to them when running. Sometimes I’d do an extra lap just to hear more. And I’d look forward to the next run.

Once the habit takes, I don’t need as much stimulation.

Another idea is political commentary slop or news. Don’t consume any during the day like you normally do (Reddit, twitter, news sites).

Instead consume it only through Youtube on your run. It’s usually stimulating enough to compel the run.
