Chris, I've done 4 spartan races in the past 2 years in all distances (sprint, super, beast).
Each one has taught me a lesson.
For general training, I think S&S will help ensure that you're strong enough for the majority of the obstacles. The swings will help condition you but I would still recommend that you establish an aerobic base (run, ruck, etc)
One thing that I'd highly recommend is adding pulling variations such as pullups and chinups to your routine. You will do a lot of climbing... rope climbs, walls, cargo nets, monkey bars, etc. You will also have to do a hercules hoist, pull a group of heavy sandbags suspended on a rope into the air and let id down easy. If you don't have a strong back with good grip, you will struggle on these obstacles. I prepared for this by doing weighted KB chinups and I was more than ready for all of the climbing and pulling I did.
If you fail obstacles, burpees need to become your friend. I'd practice those movement so that you are not unprepared when the race comes.
As Pavel said in another post similar to this, ankle mobility and strength is a must in order to prepare you for some of the uneven terrain, jumping, landing, etc.
November will be cold so make sure you dress accordingly. Expect to get wet and muddy, despite the temperature. The temperatures make the obstacles tough because of your hands... don't be surprised by this. Bringing gloves can help with some of the obstacles that are rough on the hands.
That's all I can think of for now, let me know if you have any other questions!
I love these races and plan on doing 2-3 more this year.
