"Here’s what Coach Chris wants you to do today…
Two weeks prior to the 2013 CrossFit, Jason, Garret, and Miranda ran 10 x 800 meters with a work to rest ratio of 1:1. They had been developing their endurance for 6 months and needed a solid performance test. This workout was created by Runners World and is know in the marathon running community as Yasso 800s.
See Runners World article:
This is a commonly used workout performed by marathoners in order to predict their finishing time. The theory behind Yasso 800s is that your average time in minutes and seconds for a workout of 10 x 800m with equal recovery time is the same as the hours and minutes of your marathon time. For example, if you can run 10 x 800m averaging 3 minutes and 40 seconds with the same 3 minutes and 40 seconds recovery duration, then this predicts that you can run 3 hours and 40 minutes for your marathon. Average 3:05 for the 800s and you could run 3:05 for the marathon.
Workout: 10 x 800m with a 1:1 work:rest ratio.
Jason Khalipa averaged 2:57.9
Garret Fisher averaged 2:54.5
Miranda Oldroyd averaged 3:32.9
Chad Doncsecz averaged 3:05.5
Michael Kasprenski averaged 3:31.6
"Believe that you can run farther or faster. Believe that you're young enough, old enough, strong enough, and so on to accomplish everything you want to do. Don't let worn-out beliefs stop you from moving beyond yourself." - John Bingham
