Training blues

I don't know why but I'm at a real low right now with my training, both mentally and physically. I'm riding slower and it is really noticeable on climbs, which really worries me since I used to excel in this area. School is starting next week and I'll probably end up doing a lot more riding on the trainer since it will be too late to ride outside. Trainer riding may be just the thing I need to get back on schedule and on the right path back to form for the upcoming races in September.
