I would prefer to rest/sleep every night from the beginning and if need be ride through Thursday night. That's why I asked about the times.
If like me you plan to stop at Spalding on the first night you might be at risk in departing from some subsequent controls as they are packing up, so the availability of breakfast may not be guaranteed. Most late starters seem to be planning on cycling through the first night to build up a good time buffer early on.
true, however if you used your same sort of plan but started at 12pm you would always be guaranteed food so if you are a late starter shouldn't it be the same?
with regards to riding through the first night i had no intention of doing so regardless of start time. obviously if i started in the morning the idea was to go further before stopping however from personal experience if i cycle through the first night i will suffer for it a later stage. with the PBP i found the sleep deprivation by riding through the first night after being awake all day before hand very difficult to recover from and the last 400km was done on autopilot.
redlight mentioned "Given that you are towards the tail end of the start times, one (perhaps) disadvantage of that is that you may find yourself riding alone for much of the second day"
this is also true however it is what is. all the other people i cycle with(mainly Audax Club Lincolnshire) are leaving in the morning. my plan for how much cycling to do each day and sleeping/resting is the same as it was regardless of start time. by starting later this means the less cycling time on sunday however more will be available on friday. as long as the availabilty of amenities, food etc are equal to the same extent regardless of start time then overall it shouldn't make a difference.
