IMPORTANT! - ALL RACERS AND SPECTATORS MUST PARK THEIR CARS AT THE ASSIGNED PARKING LOTS.
This will be strictly enforced by the race coordinators and the Marlborough Police. Cars will be towed that are parked in designated No Parking sections.
We have designated the below three parking lots for the main parking for this event. We will have volunteers on hand starting at 7:00 am to help efficiently park cars on race day.
Parking Lot #1 — Marlborough High School big lot (200 spaces). Enter from the Stevens Street entrance. Note: You can not leave this lot until 11:00 am.
Parking Lot #2 — Marlborough High School small lot (120 spaces). Enter from the Stevens Street entrance. Note: You can not leave this lot until 11:00 am.
Parking Lot #3 — Navin Ice Rink (451 Bolton Street, Marlborough). This lot is 1000 yards from both transition areas and offers the easiest in and out options.
