About this race

TRAINING RUN

A Free 10 & 20 Mile Training Run, brought to you by the University of Michigan Health-West Grand Rapids Marathon and Team World Vision. No Shirts. No Money. No race packets. Just a FREE supported training run on a Saturday morning. We'll use parts of the marathon course, and lots of Millennium Park.

SIGN UP SO WE KNOW WHO ALL ARE COMING!! I

We will be able to use the YMCA bathrooms, after they open at 7am, but will not be using the Community Room this year, due to construction.

NEW START LOCATION: Due to the construction at the YMCA, we will start the run from the northernmost entrance to the Devos lot, at GVSU. Upon return, you may need to do a little more around the GVSU block, to fully hit your 10 or 20 mile mark.
