The first track I've ever made and finished for Ring Racers, started with haya's unofficial UZB config until the official mapping tool and documentation got released, Grit Mountain is a track that's simple for a reason: It was made to test the power of UDMF slopes, paving the road for both a big downhill turn and then a big upwards turn - complete with many rings to run down or power through upwards.
It's a 5-lapper with few yet long turns, many sloped areas and A LOT of rings for you to keep pushing on the road, whether trying to outrun players at the start, or trying to climb up the big hills at the end.
