I came across this great video from the guys at SealFit. All of these guys and ladies are Kokoro graduates and offer some outstanding advice. If you are considering Kokoro, please watch this video and pay attention to the details. Below, I will give you what I did and where I think you should be 30 and 60 days out for Kokoro.
I agree with their advice and I can offer a little more from the perspective of an older athlete going into this event. At 60 days out you should feel pretty confident in everything. Use the published standards as a guide and then add 30-40 reps on top of the published standard as a minimum guide to progress. At 60 days out, you should be increasing your weekly mileage of running considerably while avoiding injury. Every day, you should be training in the boots and pants you will use at the event. I was doing Opwods 3-4 days a week, running focused work 2 days and rucking one day...long.
30 days out, your gear should be dialed, your feet should be hard and you should be prepared for extreme workloads of 2-3 hour constant workouts. I did the 5 miles/1000 Burpee workout, Triple Murph and lots of other challenges before the event. You should feel comfortable with a 10 minute, no movement plank and be able to do Murph weighted at any time.
At 30 days out, you should have all the work done that you need to survive the event. It is important at this time to try to heal up any injuries that you have and show up to the event healthy. Showing up healthy is of major importance to all athletes, but to the older athlete, like me, showing up compromised is not at all what you want to do. Show up healthy, strong and plan far enough ahead that you are not in a panic 30 days out, rather you are starting your taper.
