Thanks! It sounds like you have a great setup there.

I have an easy time doing intervals inside during the winter, but a harder time structuring them when I'm outside, and I live in a very hilly area.

I was thinking of doing a dirt road circuit near my house. It has a few short, steep hills and I could hit it at a challenging page for 30 minutes or more. Does that sound okay or should I do something with more structure?
