MORE THAN THE CLOCK.
MORE THAN THE CLOCK.
Some people come to race. Some come to see how far they can go. Some just want a good excuse to spend the day in the woods.
NJ Trail Series events have always been about more than finish times—time on the trails, old friends, new friends, a few cold refreshments afterward and having a good time along the way.
The goal is pretty simple: make running fun.
