It’s a Boston Marathon live-coverage, special edition of our show!

We open with GBH’s Jeremy Siegel, describing his coverage of the marathon's opening & the runner who kindly agreed to let Jeremy track him from Hopkinton to Copley.

Then, GBH’s Hannah Reale dives into some of the broader coverage & reporting on the race.

Afterwards, Edgar interviews some active marathon runners near Wellesley College.

We also check in with Curiosity Desk producer Patti Daniels by Fenway, before getting some analysis of the top finishers and big-picture takeaways from GBH’s Esteban Bustillos.

First up.... The Bad Fibs return! It’s our newsy spin on the classic Mad Libs format, with help from our live studio audience. This week Edgar is joined by our steady hand Patti Daniels, with special guest Renuka Balakrishnan to talk about her reporting on the legacy of William Dawes.
