20 Min Run (Push)

LAS VEGAS -- Wasn't sure how much time I had, so decided to do some speedwork. Actually, this is what I should have been doing here and there in the past few weeks, but never squeezed in. I know the biggest gains in time in these shorter distances almost all tie back to speedwork.

The air, again, seemed to make my lungs tighten up. Coming to Vegas as an LA runner, I wasn't expecting that. But I think the air here is worse than in the city. Weird.
