I wouldn't be surprised, 170s kill my knees. Hope yours feel better soon.
I brought both my road shoes and trail shoes to run after the farmers market yesterday - with the other errands I needed to run, the paved trail wound up being more convenient, so I did my first interval session in way too long. Nothing too strenuous, just 8 x 600 at goal half marathon pace to wake up my body and remind myself what intervals feel like.
I signed up for the half marathon in Columbus in October. Really I'd like to do the full one more time, but I just did not feel motivated to train for it.
