The 14th annual May Day 5K-10K run-walk will be held Saturday and start and end at Commerce Park Drive at Watertower Square.
The race begins at 9 a.m. with registration from 7 to 8:45 a.m. A free kids' run will be held at the end of the 10K.
All registrants will be entered to win post-race door prizes. The race is directed by Julie Pentico, Lisa Lytle and Michele Budnovitch, who hope to raise $7,000. All proceeds benefit the Relay For Life of Williamsport.
