Been a crappy workout week, but decent ride today

Riding the Mt Carmel ride with a few changes. Started off really congested, like I used to have with allergies. Oddly it has rained every day the past week, so pollen counts are really low, so perhaps molds are my problem? Anyway, could hardly breath for the first 8 miles or so, but then the congestion cleared and loosened up a lot. Felt pretty good for the rest until the end when my shoulder started to hurt again. Really need to work on strengthening my core so my shoulder won't be an issue. Overall I felt a bit better about the new bike positioning.
