How long does it take to go through the list once? If you can manage that, then you could make a smaller list of markers with x meters of the user. Keep track of how far the user has moved, and once they get near or at x meters, recalculate the list. That depends on calculating the whole list now and then being a manageable operation.

Here are some other ideas about how to do it faster:
