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.
Grit Mountain (Classic) is 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.
TIPS AND TRICKS
The starting turn is tailor made for you to hold a long drift [more so if you can use rings to descend faster] - going for a rainbow is a no-brainer if it is possible, especially if you hold on to Voltage after a lap.
With at least two flat straights and the uphills near the end, there's enough room for you to seek tether opportunities if in need of catching up.
If you decide to go for the shortcut, don't forget to fastfall quickly to land on the road and run ahead of the pack.
There's a trick panel at the end - you can either keep it for faster driftsparks in the next lap...or Voltage Drop immediately for a fast burst ahead - the latter is very much preferable if you are in the final lap.
