A ride oriented around kids but beginners are welcome also. We will ride the Bay Trail from Oracle up to Curiosity Point and back. A pancake flat, car free route that is 9 miles out and back for a total of 18 stress free miles. Bring a lunch to eat at the turn around point. Meet at the parking area across from Oracle at the intersection of Marine Parkway and Oracle Parkway.

I am guessing 3 hrs - 4 hrs with lunch and depending on the number of stops made and the wind (reason for the earlier start). There are plenty of opportunities to use the facilities and obtain water along the route.
