Race Morning Information

All runners must check-in between 6:00 AM and 6:45 AM race morning at the Santos Meadow start area. Bib numbers will be available at check-in.

In the past we would "strongly recommend" carpooling. This year we have more runners than ever. I cannot stress enough that carpooling is absolutely necessary and helpful to the environment of Santos Meadow. Volunteers will be at the start to assist with parking. Please see the parking map below.
