I tried a new pair of shoes for running today. I bought two pairs - the intention was that one pair would be my new running shoes and the other would be my go-to casual sneakers. One pair is identical to my existing running shoes, the other is a new pair that I haven't used before. I figured if they work as running shoes I'll use them, if not they can be my casual sneakers.
I really wasn't sure about sprint repeats but decided to take in a range of running styles to see how the new shoes felt. And they were very good, I'm not sure how much was psychological and how much was shoe design but I was faster than I've been in a while. Several times I checked my pace and found I was going a good 30 seconds/mile faster than it felt. My CV fitness is still a limiting factor when I lay down a lot of power but it was a really good run. Despite being a few minutes slower than my personal best it was good to get some speed work done - more like speed repeats than full-on sprint repeats and enough to get my heart pumping hard.
I suspect my legs will hate me tomorrow.....
