Sheiko has huge amounts of volume in it. Couple that with intense event training and you will be on the fast track to running yourself ragged. A crucial part in being a good strongman competitor is the ability to not only be strong in variety of events, but being able to recover from each training week. So be mindful of how much "work" you are doing and how it will inhibit your event days. Sometimes the saying less is more is true...
Setting up strongman training routines is not that hard. Reed offered some good suggestions. One thing I will say is that the more your practice with the implements the better you will become.
A good rule of thumb for any given strongman comp is that there will be some sort of pulling event (DL variant) a pressing event (log, axle, keg, DB) moving events such as yoke walks, farmers walks, keg carry, sled drag, or frame carry and then finally a loading event, usually atlas stones over bar or on to a platform.
I might suggest a template like this for someone new to strongman;
Monday: Overhead day
Wed: Squat/DL day
This way you can hit the main pressing event or events on Monday be it with an axle, log or regular bar. That takes care of one event first thing in the week. Next comes lower body. Chad Wessley Smith has suggested that strongman competitors train the DL first then do high rep squats 2nd. It is very rare that you will see a squatting event at a contest. But having strong legs and large amounts of muscular endurance in the quads, hams, low back and glutes can take you a long way.
Accesory day would be more or less a high rep, light weight workout for rear delts, chest, arms and any other areas you may need to increase muscle in.
Then for event days stick to moving events and stones. So you could set up yoke walks and farmers carry medleys, sandbag carries, conans wheel or tire flips. Then finish with atlas stones doing either lighter weight stones for max reps or loaded to a high platform, or working with the heavier stones for singles, doubles and triples.
