Boys and girls run in separate events within each age group.
Participants receive a ribbon after each race. Runners who participate in two races receive a T-shirt, and those who participate in all four races receive a medal.
For the June 6 event, organizers will give out T-shirts left over from last year.
There s no registration fee because sponsors and volunteers cover the cost of the program.
In past years, the series included five dates. It s a lot of nights for people who volunteer in the summer when we don t have that long of a summer, so we cut it back to four, Hillstrom said. We have several volunteers who have been there since the start (in 1996). They re up in their 80s.
