What makes it hard
The downhill
There's far more descent than climb, and most of it is runnable. Quads usually give out before lungs do.
Train for it: Strength twice a week and downhill repeats.
It's all runnable
There are almost no steep climbs to force a walk, so it's easy to go out too fast in the cool morning.
Train for it: Long runs on runnable trail, paced by effort.
Cold start, warm finish
Mornings are near freezing; afternoons can be hot and exposed, with up to 9 miles between aid stations.
Train for it: Heat prep in the last 3–4 weeks, and practise carrying enough fluid for the longest gap.
How long to train
Plan on 16–20 weeks for the 100K and 12–16 for the 50K if you're already running 4–5 days a week. In the last 2 months, make your long runs finish downhill.

Is Black Canyon a good first 100K?
Yes, if you respect the descent. It's runnable, well supported (9 aid stations) and has a 20-hour limit, but runners who skip strength and downhill work often find their quads finished early.
