Spinervals 27.0 plus a bonus swim!

I'm unexpectedly traveling this weekend, and so have had to make a few amendments to my workout schedule. I was supposed to swim 1100y tomorrow, but may not be able to so I swam it today. Warm up with 100y drills and then swim a straight 1000y.

Spinervals 27.0 was a good effort. I was asked to do a similar effort earlier this week and I miscalculated my LT by 10bpm. Unfortunately (and uncharacteristically), I estimated too low and didn't work hard enough. Today, I listened to Coach Troy and achieved better results.
