Start times are limited by the business hours of the host, which can be a restaurant, a motel, a store, and even a police station or planetarium. You just ask for the stamp and stamp your distance book when you are finished. You still go at your own pace. The good part about regular events is that if you want, you can walk with others that are there to walk the event. There is usually food and drink at family prices at the events.
Clubs usually have two to three events per year.
One of ours is always on National Trails Day - the first weekend of June. Then we have group walks where we all start out together - usually either 9am or 10am depending on the time of year, but it can be in the afternoon like our Christmas Lights walk in Oxford. Plan to eat together afterwards on these walks.
