Ride planning
Build an Out-and-Back Route
Choose a clear turnaround landmark and identify earlier places to shorten the ride. That makes the plan easy to adapt when time changes.
Put it into practice
Think about the return direction as well as the outward leg. A hill or exposed segment may feel quite different on the way back.
Before your next ride
Use a simple checkpoint such as a park entrance to tell companions when the group will regroup.
