This year will mark the 30th year that Grand Rapids has hosted the "River Bank Run". This is the premier 25K run in the US.
Why 25K? It makes a nice out-and-back route along the Grand River.
And, yes, they are using the clock-wise route this year that puts the awful hills near the end.
This morning they hosted a Training Run that covered much of the course. Most of the runners were bundled up for the cold.
