Uphill, downhill, standing start, flat, clips, grass. There is so many to do. It's tough to get your head wrapped around it.
I know a lot of guys have their own distinct programs but I think the core is definitely: flat ground, downhill, standing start and sprinting while already going fast. How many and how far is also another distinction. Full speed is good to go longer while standing start is more like a snap and then sprint to the first jump type of training. So continue to look out there and see what you can find!
