Nice ~250m hills. Fun to use something close by rather than going to the track all the time. Got a ski trail section I’m starting to use for repeat workouts — Stairway to Heaven. Will set a goal of so many per week, month, season once I try it for awhile. Addresses my biggest weakness, hill climbs.
Hills have always been my biggest weakness, although pretty much everything is a weakness these days. It is interesting doing the driveway, because it exposes the micro variations in slope along the way. Those also get exposed a bit in the winter anyway, because there are a couple of steeper spots where wheels often spin if there's snow or ice.
