Los Altos Runners At the Boston Marathon

A day of celebration has turned into tragedy and chaos as two explosions take place about an hour after the first man crossed the finished line in Boston Monday. The explosions reportedly killed two and injured dozens.

The Mercury News' reporter Daniel Brown reported that Los Altan and Runners World founder Bob Anderson, who completed his first Boston Marathon, had an emotional reunion with his son, Michael, in their hotel lobby.

According to the Boston Athletic Association website, nine Los Altans registered for the race. Five had already posted results between nearly three and four hours after the start of the race.
