i reckon you have a better chance of doing all 280 miles solo.
have done a few 200mile + overnighters and it's the needs of the group that add time - punctures, loo stops, food stops etc. basically multiply all the ride-stopping events you will experience by the number of people you are riding with.
pretty sure these outweigh the morale boosting benefits of having team mates.
