Three Dorchester runners - Michael Crowell, 37, Scott MacKay, 37, and Katie Markunas, 28 - are putting in long hours of cold winter training to get ready for the April 20th Boston Marathon. The three are part of a team that will raise thousands of dollars for those who suffer from life-threatening liver diseases as part of theAmerican Liver Foundation's Run for Research (RFR) team.

To date, thousands of RFR team members have raised over $12 million dollars for critical programs. The 2009 RFR team hopes to raise over $1 million. To make a donation to a Run for Research® team member from your town, please visit liverteam.org.
