Intervals are here

It's been a while. I almost forgot how much I hate/love them. I can't decide if doing them on the trainer makes them better or worse.

It does have some benefits. Once it's warmed up, it stays consistent. No stop signs or hills. Don't have to pay attention to traffic. The surface never changes. No potholes or railroad tracks. No bad weather.

On the other hand, it's a trainer. And I'm sweating on carpet.
