up river/Warming Up: As you head upriver
you will notice the marshalling area on the other side of the river.
Do not cross into those lanes and be sure head up past the large buoy
which is next to the painted rocks on the Prince William shoreline.
A marshal will be there to check you in and give you an approximate
start time. Should you require more time to warm-up, there are over
8 miles of river upriver, but be sure to stay close to the marshalling
area once your event draws near.
