We are from Kansas City and are thinking of biking a portion of trail with our children this fall (ages 2, 5, and will be 8 soon). We regularly do family bike rides with my husband pulling the younger two in a trailer while my oldest rides a trail-behind bike with me. We typically bike to a park about 6.5 miles away (very hilly miles I might add) – play for a bit and return home. If we break up the day and check out the sites along the way I am confident we could do twice that if not a bit further. Any recommendations for where we should start and end would be very appreciated.
