From our Facebook Group, Squaddie Chris Hughes asked: 

Can someone explain to me what it means to swim "without haste"? How is this different than just swimming "fast"?

From Matt Dixon: 

If you tell a swimmer to go fast -- it is very common for less experienced swimmers to just fight. They tighten up, and ramp effort but the result is no more speed. Increase effort without increase speed isn't good (obviously). Swimming is a RHYHTM sport. It is about timing and connection, which is common in sports (golf, throwing, swinging a bat). More force doesn't equate to more power if timing is off. With this in mind, we want you to feel and learn increase effort to equate to increase speed. How? several ways, but a few considerations: 1. Speed is the length of pull, the amount of water 'held' and the speed (stroke rate) of the pull). To maxmize we want high 'grip', timed well with great force... repeated and quickly as sustainable. So RHYTHM remains the same (timing) but the TEMPO increases. This is where David's thought of the tempo trainer is good. It isn't just about increasing stroke rate, it is about maintaining the length of stoke, timing of stroke and force of pull to get to faster stroke rate. the swim without haste is simply a descriptor. Don't think you are doing great because you are simply trying hard. Pursue connection, timing and increase effort without introducing tension/angst etc. Like Purple Patch: FLOW. RHYTHM. SYNCH. Lovely words..:) Boil it down: I want awareness and feeling that high effort/tension will not equate to better swimming!
