Since this is everyone's Long Course (swimming) and triathlon birthdays, my Masters swimming group did a 5500y workout in honor of one of the long-time members. The workout, as she wrote it:

1000: 400 swim, 300 pull, 200 kick, 100 choice
900: 3 x 300 pull
800: 4 x 200 IM as odds 25 drill/25 swim; evens 25 kick/25 swim
700: 7 x 100 on descending interval (1:45, :40, :35, :30, :25, :20, :15)
600: 4 x 150 Kick IM order per 150
500: 2 x 250 IM (25 fly, 50 back, 75 breast, 100 free)
400: 4 x 100 choice
300: 2 x 150 IM as 25 fly-25 free, 25 ba-25 free, 25 br-25 freee
200: 4 x 50 @ :50, climb out and start from blocks on each
100 easy

5500 short course yards totals

And, so you don't think this was all about master swim dorks, there were several top-level AG triathletes in the workout, including a 2013 Cozumel KQ and a World Olympic Distance AG qualifier. They did all of it, INCLUDING THE KICK and STROKE!

Happy Birthday to everyone!
