A runner from Madison says his hotel room shook with the force of the blast at the Boston Marathon.
David Meixelsperger finished the race about 90 minutes before the explosion Monday.
He sent an email to customers of his Madison running store and friends in the running community letting everyone know he was safe, but that he couldn't send or receive calls on his cellphone.
The fiance of Democratic state Sen. Chris Larson's brother also ran the race. Larson says Kristen Kamm finished 25 minutes before the explosion.
Larson says he saw his brother post on Facebook that they were both OK following the bombing. He later spoke with him by phone.
Larson says he's "very, very relieved."
