I have good memories of substitute teachers, and they mostly follow the "oh, we're going to get off easy today" narrative. They were all nice, probably a bit scared, but they pretty much stuck to the script of not rocking the boat. Here at MIT Masters, we have had a series of substitute coaches on deck this summer, something that all of us appreciate very much. And while they are all nice (important trait #1 for a sub), they are definitely not scared of us and most assuredly did not stick to the script, particularly in the first couple weeks. In fact, there was a strange competition between the subs as to who could provide the most outlandish workout. 800 fly? Yep. A matrix where you had to be able to count and swim? That too. A pace-line catch-up thing which was meant to build lane camaraderie? Fun times. I'm frankly surprised that we did not have a drone dropping off a set and then zapping us when we didn't make the interval (it's MIT: anything is possible). Thankfully, things have calmed down quite a bit and substitute favorite Derek was on deck today, with special thanks to E for writing up the workout and Coach Bill for preparing it. I will say that the past few weeks have served to reenforce why I love swimming at MIT Masters: Wonderful lane mates/teammates and coach Bill.
