I've found that in training I actually get better results with shorter distance carries using heavier weights. I'll go for distance as a warmup, as far as I can get with just over 100 lbs until it falls from my hands, but after that the bulk of my farmer's walk workouts tends be be around 10 sets of 20 or so steps at a time.
I also don't bother practicing the turn other than whatever might be necessary during the warmup set. I might do a few turns with a poundage around what I might use in competition but it's very minimal at best. The turn is a pain in the ass and it's going to be a pain in the ass whether you've practiced it in training or not. I'd rather practice with the heaviest possible weights so that whatever I end up using in competition feels that much lighter, including during the turn.
Another thing I do differently from most in training for the farmer's walk is to use straps for my heaviest sets. A lot of people, especially online for some reason, see this as almost blasphemy but that's because they view the farmer's walk as a grip exercise rather than a total body strongman event. When you use straps it takes the grip out of the equation and lets you use more weight so you can focus on other areas that might be a weakness that you may not have even thought about otherwise. The shoulders, hips ankles and feet come immediately to mind. Recently I worked up to 295 per hand for around 20 steps using straps and I think I can go even heavier than that. That weight is pretty light for a heavyweight strongman competitor, but I'm not a heavyweight.
You can't really see the weights in those pictures but on each side there's a 50, two 10s, another 50 and then two more 10s. That's just the way it ended up being that day. The handles themselves are 15 lbs each.
So there you go. My treatise on the farmer's walk. Don't whine that I don't post enough training information.

Heavy farmer's walks with straps have made my ankles indestructible.
