Mix of simple Bobsleigh training tracks. Can be found in-game in the TM Training club, alongside many other training campaigns. Some are unique tracks, while some are repetitive, emphasizing practice of a particular entry and/or turn style.
I tend to prefer good "flow" bobsleigh, but some maps have intentionally weird or awkward turns/elements (e.g. maps that were initially intended for Rally or Snow Car bobsleigh). These awkward elements can be useful for training and experimentation, especially for RMC/RMS. It can be interesting to explore all that Bobsleigh has to offer. As I add new maps over time, I aim for the vast majority of them to be playable "flowy" bobsleigh.
Author times in general are on the difficult side for RMS, but I typically try not to put any more than 5-10 minutes into AT setting; I'm leaning towards making future ATs easier. All ATs were set with the Bobsleigh physics from the 3rd ice update, i.e. the physics as of mid 2024.
