Lately, my 10K time had been nowhere near my best times of 58:27 and 59:20 and my recovery period had been less than comfortable. The outsoles of both the Adidas PureBoost and Asics SortieMagic are wearing out, so maybe it's time to get new shoes.
Unfortunately, the Asics boutique did not have SortieMagic in stock anymore, so I had to find another model. I checked out a few stores and ended up with a pair of Brooks Ricochet.
Not as thin as I prefer, but really nice ride for slow runs. I like them.
I tried running fast with them and only got 59:59 and subsequent tries were slower. I retried harder and eventually I was able to get 58:50. Yeay! Unlike the fast-feeling SortieMagic, I had to consciously make the extra push to get a good pace from the Ricochet.
Recovery period was good.
Lesson learned: When recovery period is painful and long, it is probably time to get new shoes.
And the day before yesterday, I was hoping to do another sub-60 minute 10K. I felt great physically and the early morning weather was nice. I checked the stopwatch periodically and gave it a push in the last 2K. I did not intend to make a new best time, so I was very surprised to see the time.
So to-date, my best times are 57:50, 58:27, and 58:50. I think that is enough fast running for a while.
