How can I adjust the pace for a route

Problem: You have a route and you only want to adjust the pace. The checkpoints should then reflect the new pace.
Solution: Select the route and open the info pane. Enter the new average speed.
Tip: The info pane also displays an arrival time. It's based on the duration (by speed and distance) and the current time. This is helpful if you want to finish a route before sunset and you need to know when you should start.
