Each year, I have the same issue. Once the weather breaks I don't do well with my running. I have been in such a groove with running 3 days a week in the wee hours of the am. Last week, I made it once. This week I am aiming for twice.
My half marathon is in 12 days. So I am sure the taper isn't helping.
I run so much better in cooler weather, so you would think I would be all over these cooler temps...yeah, no so much.
I still have goals for this half marathon...excited for it...
