i am going on my first multi-day tour in september; i am doing the lake champlain bikeways 363 mile principal route. i hope to do 50 miles a day. is this too much with all the gear im going to be taking along with me? how many cubic inches of storage capacity should i have for my gear for a trip like this? it will be "self-contained" and i will not be staying at b&b's. i am fit enough for century rides. so the 50 miles a day doesn't seem to be too much, but im not sure. currently i commute around 40 miles a day 5 days a week. i was thinking of maybe 4000ci of storage along with putting some stuff on the top of my rear rack.
