50 50's on :50?

we've got a 50th birthday at swim practice tomorrow. It's also our last day for two weeks until the pool re-opens. Does anyone have an idea of a really fun workout for an hour featuring 50's? We've got a diverse mix of fast and less fast swimmers. Thanks!

  • Hmm, 100x100 on 1:00 or 100x100 on 1:40? One's too hard, the other too boring.When you are 100 years old and give this set a try you may find both intervals to be a challenge. I’m hoping the 75 X 75’s on 75 (1:15) won’t be insurmountable when I’m 75.
