ICYMI: Boston Mayor's Chief of Staff Proposes to Girlfriend After Running the Marathon

Editor’s Note: This was originally published on Monday, April 20.

A Boston Marathon runner crossed two finish lines on the day of the April 20 event.

Not only did Dan Koh, Mayor Walsh’s chief of staff, complete the iconic race alongside his girlfriend, he also proposed to her after the lovebirds reached the end of the route at Boylston Street.

Koh and now-fiancée Amy Sennett ran in support of the Martin Richard Foundation, a charity created in memory of the 8-year-old boy who perished in the Boston Marathon bombings in 2013.

After the couple finished the race around 1:45 p.m., Mayor Walsh stood just past the Boston Marathon finish line and granted Dan with the ring.

Koh arranged to have different friends hold up a poster with a line from a poem he wrote for Sennett at every .1 mile of the race, starting at mile 24.8.

Boston.com listed the text from each of the 12 posters:

• Amy, you’ve changed my life
• We’ve been through it all
• From Boston—(Kaya!)
• To DC—(M Street!)
• To New York—(Cramped Studio!)
• To Philadelphia—(Talula’s Garden!)
• ... and back.
• There’s a lot we have left to learn
• But I know one thing for sure
• I love you, and will love you, forever
• You’re the answer to all my questions
• But I have one question left to ask ...

And she said yes to that question.

Koh, who met Sennett in 2009 at Harvard Business School, actually had one of the mayor’s speechwriters look at the poem beforehand.

Monday was the pair’s third time running Boston together.
