I rode very hard on the way home last night and paid for it this morning with stiff legs. It was 10C when I left the house so shorts and jersey were adequate. There is a local non-official weather station that gives real-time temperature and wind. I like to check that site when the hourly temperature for the regular forecast is borderline for a clothing decision.
This afternoon I'm stopping by the LBS to talk details on my new winter bike. I gave them the full details at the end of April. When I told them there was no need to rush it I wasn't expecting it would take 5 months. Since my MTB is in pretty good shape now I might look at getting a pre-built fatbike rather than building a new custom MTB.
