Covering 1100 miles in roughly 9-10 days (at 100-150 miles a day) isn't much different than completing the LEL (London-Edinburgh-London ). The LEL is 1400 km (850 miles) long with a time limit of 116 hours (about 5 days). So that sort of thing is doable, BUT the riders who do the LEL are generally experienced long distance cyclists who have ridden at least a Super Randonneur series.

Covering a long distance in a short period of time is not about seeing the scenery or bakeries or relaxing and enjoying people's company or whatever, it is about accomplishing a goal which is just as legitimate a reason for riding as seeing the country, visiting historical places, or whatever.

If the OP is serious about doing this (and we may never know because he is one of the masses who proposes something like this and never returns), the OP needs to take it seriously and get out there and ride lots for the next few months.
