That practice was harder than expected

Today was did 30 minutes of dryland followed by a 15 minute boxing session.  The pool workout looked pretty easy:

4 x [25y bucket with :10 rest + 50 All Out (Purple)]

Each round followed by 400 relatively easy swim/kick stuff.

The rounds were:

2 rounds with fins/paddles
1 round with fins
1 round with no equipment 

I underestimated how exhausted I would be by pulling a water filled 20 gallon bucket 25 yards, which took 15-20 seconds each time.  I eventually realized that if you add a race start, you're really only swimming about 15 seconds in the first 50 yards of a race.  This means that the 50 all out was pretty much a second 50 of a 100 yard race.  It was a rough set.  My 50 yard times in all four rounds were:

23.7
23.1
23.3
26.1

I'm glad it was only four rounds.  That was rough.
