The response to the Marathon bombings has been remarkable. In ways large and small, the Boston community as well as the world community have let it be known that we will remain strong -- Boston Strong -- and stand by the victims.

The One Fund has emerged as the primary way to help the people most affected by the tragic events. If you want to let your voice be heard and have your dollars make an impact, consider participating in this Sunday's Circle the Track event. To be held at the Harvard University Track, participants will either run five miles or walk a lap. (Actually, the folks at the Charles Hotel who are organizing event say that participants could skip the exertion and simply chill out in the company of other donors if they prefer. It's really the contributions to The One Fund they are after.) Everyone who donates will receive a T-Shirt and breakfast treats.

You might be thinking, "Hey Arthur, it would have been nice if you gave me more notice about this event." First of all, since when have we been on a first-name basis? And second of all, this event only came together today, so I'm sharing it as quickly as possible. It's emblematic of the sense of purpose, urgency, and action that has characterized the Boston Strong attitude in the days following the Marathon. There have been a number of rapid-response events in support of The One Fund. What I especially like about this one is that it incorporates running and demonstrates the conviction of Bostonians and those who are united with them that we will not be intimidated. After the Circle the Track event, participants could enjoy the nearby annual MayFair in Harvard Square to be held outdoors from noon to 6 p.m. in multiple locations. There will be lots of free music and dance on multiple stages as well as crafts, street art, and more. Perhaps you could plan a meal at Henrietta's Table or Rialto, both located at the Charles Hotel in Harvard Square.

By the by, speaking of large ways to help and events coming together rapidly, be on the lookout for info about a proposed May 30 concert at the TD Garden that will benefit The One Fund and feature Boston-based performers from the 1960s to the present. More details to come.
