Rust(buster) Never Sleeps

Bad Neil Young pun I know, but I had a good tempo rustbuster on the track today so why not? After a 2 mile warm up with strides, I ran a 4 mile progressive tempo with the goal to start slow and run each mile a little faster than the one before without going over 90% Max Heart Rate Reserve. My splits were 6:36, 6:28, 6:22, 6:18. My heart rate got to 85% by the end of mile 2 and I was able to comfortably hold true threshold pace over the last 2 miles, never in danger of going into the red (over 90). 2 mile cool down made it 8 miles for the day. Wore new flats in the tempo portion, New Balance RC 1400s and I like them a lot. 7 ounces so slightly heavier than some models I had been wearing but much better for my calf and achilles as the cushioning is really good. They're built on the same last as the New Balance 890 light weight trainer, which has been my favorite training shoe over the last few years. Here's Oasis covering a Neil Young classic!
