Over the years, SERC has put on local races, held many social events and provided training opportunities for both novice and advanced runners. Whether you are a competitive runner, seeking to qualify for Boston or training for a half-marathon, marathon or ultramarathon, SERC welcomes your membership and encourages you to join us for our group runs.
