It would really depend.
Are you the type to stop for photos? How often do you stop for food/bathroom stops etc. How old are you? How many miles do you ride in an average week?
End of June it will likely be fairly hot and humid, so I would say trying that kind of distance is best done at a cooler time of year. Plenty of hydration will be key and to cover that distance you'll have to be riding through the worst of the heat in the mid-afternoon.
What I would say is get through Day 1 & 2 and then reassess where things stand, how trying of a time the ride has been on the first couple days, whether you're dealing with a case of major saddle sore, flats, broke spokes or general bad luck or bike troubles. If this is the case, I'm guessing aborting your plan would be your best option, unless you're fond of tempting fate.
It certainly ambitious. Doable, not so sure..
The only way to really find out is to go out there and give it a shot.
