Rollers can be so much fun.
Not really, but they are a good change of pace from running. I don't know how my wife does it, running as much as she does, but good for her.
Rollers for 45 minutes with 1 leg pedalling drills was good for me yesterday.
Today, snowshoe running. Yup, snowshoe running. Take something that isn't terrificly fun, and make it harder. That is snowshoe running. But, maybe I built some character today.
I sure hope so.
