    emails: I ran Boston in 2011 and it is horrific to think of running down that finishing straight after 26 miles and something like that to happen. I am running the London Marathon for the second time next weekend and I feel sick to think that someone would consider doing this to such an event.

    Jennifer Treacy from Malta, New York

    was running the Boston Marathon for the first time and filming her progress. She managed to capture the moment the explosion went off. She says: Initially I didn't think it was a bomb, I just thought it was fireworks or something - a celebration, a happy event. Then it became quite evident that it was a bomb and I ran to seek cover. Myself and a lot of other runners on the street ran into a building lobby and there it was just chaos. There was a sense of panic because people were separated from their loved ones. My main worry was my 13-year-old son who was there at the time. It was hard to find each other initially, and then it was difficult to get out of Boston.

    This year's marathon attracted runners from every US state and more than 90 other countries. Many have been telling their story.

    British runner Keith Luxom, who had already finished when the bombs went off, told the BBC the jubilant mood changed to one of "shock, horror and total disbelief that people would target this great institution".

    "Lots of runners went to the hospitals and offered blood," he said. "People were sharing mobile phones so people without one could phone home."

    "There are two pools of potential suspects - the usual suspects, people who are known and on the radar, but then there are those who are operating below the radar - the lone wolf who might be inspired by God knows what to create an action such as occurred yesterday, and the unknown are more difficult to track down."

    After a minute or so without another explosion, she said they headed to a Starbucks and out the back door through an alley. Around them, the windows of the bars and restaurants were blown out.
