I’m speechless. I can’t stop thinking about the sadness … and madness … from today’s Boston Marathon.

As a former Boston resident, I mourn for the injured and for the dead and cannot stop thinking about the feelings sweeping the city on this normally joyous occasion. I think about all my fellow Bostonians, who were spectators and runners on what should have been a beautiful day.

As a runner, I mourn for the injured and for the dead and cannot stop thinking about those who devoted months, and years, to training and have not yet got to realize their dreams of crossing the finish line and running Boston.

As a family member of runners (not racing in Boston this year), I mourn for the injured and for the dead and cannot stop thinking about those who spent months supporting their spouse/sister/brother/mother/father train and looked forward to cheering them on today, but instead were forced to send frantic texts as they waited to hear of their loved ones’ whereabouts.

Thinking of all those affected by this tragedy and keeping everyone in my prayers. My next run will be a grateful one and I will certainly be thinking of all of you.
