Road Cycling: The Royal Oak Michigan (65 miler)

Hello all.. New to the site and looking for some info on this training ride I found here. http://www.mapmyride.com/ride/united-states/mi/royal-oak/715918568 Would like to know what time and days this ride takes place. Any info would be great. I'll be visiting family this summer and and would like to maintain my training schedule for an upcoming Stage Race in Lancaster PA. (Tour Of Christiana). I'm very close to getting upgrade points to Cat.III and would not like to blow it on Grandma's home cooked meals. Thanks lee/nyc Sids-Cannondale racing
