Although pre-determined by locations of touristic centers, checkpoints are pretty evenly and logically dispersed on the route. This also goes for full lunch course at CP3 during the first day and common resting place at CP4 for the first night, that should suit all but the most dedicated riders.
From then on, the tactics will determine the remainder of the logistics but another full course lunch, this time on CP6, should again suit most of the riders. Riders in the brevet category would probably look into resting again at CP7 or somewhere along the route towards CP8. This will enable them to reach CP9 at the end of the third day and have a short run in towards the finish early on the day four. Quicker riders might even finish during the night.
As for the race category, where every minute counts – riding strategy will be quite different and the decisions as to what to do on CP3 and when to take the next significant rest might be quite crucial to the remainder of the race.
