An expensive run

I can’t tell if these workouts are too hard or if maybe this is just what hard workouts feel like at my age now. I hit some of the paces. But I had to go to basically max HR to get there. And I’m worried that this was too expensive of a price to pay for what I want to get later.

Disclosures: I’m partnering with Runna on my buildup to the half marathon in Houston. I have a set list of deliverables on this partnership. This doesn’t fall within that specific set, so I’m not technically getting paid for this. but I’m gonna mark this as a sponsored post anyway.
