MARKING

All participants can pick up a copy of their appropriate course map on race day.

Each course will be marked with colored ribbons that are unique to their distance, so that runners know they are on the correct course.

AID STATIONS

As with all of our races, aid stations will be fully stocked with water, sports drink, gels, pretzels, candy, etc.

Runners who may need more water, should carry their own water bottle.
