She's a Professor and Black Girls Run Ambassador, and This Is Her Workout Routine

Where: Mystic River State Reservation, Medford, MA, and Somerville, MA

When: 6:06 a.m.

Tiffany's Notes: "I'm feeling nature this morning, [so] I ran along the Mystic River Reservation. I reminded myself to stretch for at least 10 minutes before I started running. Today's run was a mixture of run and walk. On my path there was a turtle and I thought, 'Why am I running fast?' I was reminded to slow down a bit. Then I saw all the fowls: geese, ducks, and swans, all together on the river — when does that happen? I wanted to walk a bit and enjoy the beauty. Besides finding love, there are reminders around inequalities and justice."
