Next Friday April 30th is a very special day. Not only is it National Hairball Awareness day (http://www.answers.com/topic/national-hairball-awareness-day) but it is also my birthday and I’m turning 30! We are going to have a little party at COP to kick off my birthday weekend and you are all invited. Pops has kindly agreed to put together a special WOD for us that will incorporate the number 30. Please note it is my birthday and even though I have no idea what the WOD will be, Pops has been given strict instructions to skew the WOD heavily in my favour, so don’t count on seeing any box jumps, thrusters, rowing or running. We will have food and drink on hand and prizes will be awarded to the top male and female participants.
Hope to see you all out!

Sleep Your body needs time to rest and repair itself in order to stay healthy. The best way to accomplish this feat is to get enough sleep.
Natural Sleep Cycle
Besides being the primary hormone involved in directing the functioning of the immune system, cortisol also dictates when we should be active and when we should rest. Cortisol levels follow a 24-hour cycle, peaking as the sun rises and tapering off as the sun sets. And as cortisol levels rise, we are given the energy to begin our day. As cortisol levels drop-reaching their lowest point about three hours after dark-our bodies enter into a period of rest and recovery, physical repair, and psychic regeneration.
Sleep, Rest and Recovery
Our immune system functions optimally if we go to sleep by 10 p.m. As we sleep, physical repair takes place between approximately 10 p.m. and 2 a.m.: Our immune cells patrol our bodies, eliminating cancer cells, bacteria, viruses, and other harmful agents. Then from about 2 a.m. to 6 a.m., we enter a stage of psychic regeneration. During this time, the brain releases chemicals that enhance our immune system. Throughout the night, we experience rapid eye movement (REM) sleep states and non-REM sleep, alternating between light sleep and deep dream states. This is how we process the mental and emotional events of the previous day and refresh our minds for the day ahead.
Most people need a minimum of seven or eight hours of sleep to accomplish all these tasks. Without sufficient sleep, the immune system is hard-pressed to keep up with its repair work. This creates the opportunity for disease processes to begin. Moreover, if cortisol is elevated at night-say, because you are anxious-these immune functions can become compromised, which ultimately leads to illness and disease.
An Example of the 24-Hour Cortisol Cycle
Have you ever wondered why your cold or flu symptoms get worse at night? It's because cortisol production regulates your immune system on a 24-hour cycle. As cortisol levels drop at night, your immune cells become highly active. The immune cells kill large numbers of bacteria and viruses, causing greater mucous production. As a result, you experience more congestion and coughing as your body attempts to get rid of the mucous.
At daybreak, when cortisol levels rise, the activity of the immune cells tapers off. The immune cells then reset and recondition themselves in preparation for the next nightly cycle.
Problems arise when cortisol levels are out of balance-say, when you fly to a different time zone-thereby compromising the cycle of immune function. As you can see, sleep/rest and recovery is essential for our bodies to repair and maintain optimum immune function.

CrossFit Football total
A great video of the "CrossFit Football Total" workout at the B.C sectionals in Squamish.
Run 100m within a 30 second time limit for 10 minutes.
The faster you run the 100m, the longer rest you have before the next 100m run begins.
If you can't run the 100m in the 30 second time limit for any round in the ten minutes you are eliminated.
Start the first 100m run at the corner of Ash st. by striped post on the bicycle path, and run down path (east) in front of C.O.P for 100m. Then next 100m run back to Ash st. starting point and repeat.
