Overall general training that I follow:
Get your running technique down-pat. Run tall and light, preferably forefoot striking under the body, use your arms on the uphills. Think about your technique all the time.
Work your core as much as possible. I do a 45 minutes core workout 3 times per week minimum.
Train to be an effective power-hiker. When you get to part of a run too steep to run/not worth wasting energy running, power hike like no tomorrow using your arms and powerful strides.
Run long at least once per week (4hours + at least) amongst your other training runs.
Race nutrition is vital, practice it on your long runs. Eat early and eat lots. In TNF100 I had a gel every 35minutes and chomps sporadically also and 2 bananas and 1 blueberry muffin (these real foods at checkpoints). I consumed 3L of GU roctane electrolyte endurance drink, ~1.5L of Hammer perpetuem and 300mL of coke during TNF100 along with ~1L of water.
Get your race pack weight down. Use checkpoints effectively for this regarding liquids. Soft flasks on the front of the pack tend to be best for me.
