We have added a winner category this year! New this year, we will have a male and a female winner from each of these age divisions: 
1) 17 and under
2) 18 - 49
3) 50 and over

First place winners from each category will win one of our beautiful canvases of a picture from somewhere within YRSF taken by a local photographer. NEW THIS YEAR: 2nd and 3rd place winners in each category will receive a prize as well! 

Races will be timed again this year.

Due to the use of existing trails the distances are not exact.
