I'm starting to relate to the comments about mental health and spending much time on the trainer. 3-4 hours would be really tough. And I think I have a better idea about what base training is now and can see how having a goal for a trainer workout would help in staying motivated. I think I need to get more confidence riding on the gravel that's all over the roads in the winter. It just doesn't look like any fun to fall on, but I need to get out on one of the nice days.

Thanks again for the advice!
