I'm not for a separate course. Don't get me wrong it worked when score has done it to separate the bikes and some of the sportsman classes, but.... as a long term solution the best scenario is separate events. I know this raises all types of issues with permitting and costs but it's the best fix there is. Secondarily, longer splits at the start; 2 minutes or more would be awesome. But again this creates additional problems for the org and classes finishing in the middle of tge night, which some are opposed to.We need events you must qualify for where everyone gets a 2 minute gap.
If SCORE/BITD had the ability to run an sportsman circuit and a pro circuit we might be able have less dust, more enjoyable as well as safer racing.
