Spend the CLAM BUCKS
that you get with your event registration at participating merchants during the week of the event.
What are Clam Bucks?
Clam Bucks are wooden tokens worth $1 each. They can be spent just like cash. Each participant receives 5 Clam Bucks with their race bib.
We provide an additional 5 Clam Bucks to participants who have their packet mailed or choose to pick-up their packets on Thursday or Friday to help us reduce crowding at packet pick-up.
When can Clam Bucks be spent?
Clam Bucks are valid for a full week, starting on the first day of race packet pick-up, Thursday. The final day Clam Bucks can be spent is Wednesday after the race.
Where can Clam Bucks be spent?
Clam Bucks can be spent ONLY at participating Chamber member businesses. Businesses will be given a sign that shows that they accept clam bucks, too. Limit: 5 Clam Bucks per person, per business unless business allows otherwise. List of participating businesses will be posted nearer to the event.
