The Boot is reporting that Dierks Bentley's wife Cassidy Black will be running in Monday's Boston Marathon.

She'll be running to raise money for a Nashville homeless shelter for families called Safe Haven.  You can donate to the cause HERE.

Can we expect to see Dierks in Boston to cheer her on? Not sure.  But you can get the full details on it all HERE.
