I love all of the events

I love all of the events from Run.Windsor! They are so fun and well organized. All of the people involved are encouraging. I feel so blessed to have something like this in my small(ish) hometown. Keep up the great work!

Makes Running Fun

Since I moved from Texas, I have struggled with finding a workout ‘family’. I am the type of person who needs the motivation to keep moving, provide accountability, and make running fun. Mandy has created a great network of people who come from all backgrounds, athletic differences, and has a plan for every body.

Highlight of My Time

Run.Windsor has been a highlight of my time in Windsor! Their tagline, Stronger Together, is so true! They share their struggles and their triumphs, and truly support and encourage each other! I am blessed to know these women!
