Bismarck Runners--Dave Nash and Lynn Beiswanger were both in Boston when the ground shook.
Dave Nash / Boston Marathon Fan: "By the time the fourth person ran by, the said, two bombs just exploded near the finish line. I said, this can't be. You must be mistaken."
Lynn Beiswanger / Boston Runner: "About a block from the finish line and I was actually on my way up to shower and clean up and anxiously await the arrival of all the team members. Instead of a celebration, it turned into something that we were totally not expecting."
This was Beiswangers 13th year in Boston--Nash's 7th.
All 15 Bismarck runners had all crossed the line before the 1st bomb went off.

Dave Nash / Boston Marathon Fan: "The whole race has been designed with runners safety in mind from the get go. We have EMT's we have ambulances on stand by that's never more than 4 miles from the furthest point from where they are sitting. We will ask people to be more award of something strange so they can call race headquarters and we can get the police out there to look at it."
Lynn Beiswanger / Boston Runner: "We have just raised our own awareness of things that don't look like they are in the right place."
Their advice to runners who are worried to run is to run your race.
Lynn Beiswanger / Boston Runner: "We would continue to encourage runners to do what they have been doing. Continue to attend your events and enjoy it and enjoy the day to it's fullest."
