Sansa Clip+ and podcasts - fast mode?

Main question: Is there a speed setting for listening to podcasts in “fast mode”, such as double or triple speed? I saw something mentioned for audiobooks under settings in the user manual PDF but not for podcasts.

I’m thinking of getting one of these for running. I put in some extensive miles in year round marathon training. Some rain and sweat could be an issue. Any related tips or other comments would be appreciated as well.

Thanks!
