Tougher week-easier week

Cut down the volume this week, due to a range of different factors. Logged some good hours the week before (see below) and thought an easier week with focus on doing quality work and feeling strong for every workout would be timely. Also, the weather was bizarrely cold which disencouraged me from doing any bricks before sunday. And then, this usual problem – lots of work getting in the way.
Been training a lot on the bike trainer. Or, not a lot, but it feels like quite a bit, because the trainer makes for much more intense training than riding outdoors. I do think it's smarter than going outdoors in -15 celsius for skiing or, for example, commuting with the bike.
