There is a running race on Memorial Day, Monday, May 26 2008 at the Jensen Nature Park in Syracuse on Bluff Rd.  In the past, this race has been held in Kaysville but has been moved to Syracuse due to construction. I personally think the Syracuse trail system provides a great place for a run.  Most of the half marathon course will be on the  trail system that runs through Syracuse and West Point.    Registration for the Memorial Day Classic Half marathon, 5K and Kids K is available at Striders or online at active.com or http://www.stridersrunning.com/
