Is the ride the weekend of the 14th? If so, I suggest that this weekend you get in a ride that's 70% of your event distance and 70% of the event climbing. For the next week I would keep training as normal. The weekend before the event you should start tapering, keep your long ride to 50-70% of event distance and climbing. The next week should be kept to easy recovery riding, resting up and fueling up. Go for a very light ride the day before. You should be riding the event in an "endurance/tempo" zone, for me that's about 72-78% MHR. Why don't you want to use the rest stops? You need to fill bottles, eat and use the john, just try to keep the stops short. What event is it and how much climbing? I will be doing Breathless Agony this Saturday (114 miles, 12,000' climbing).
