One way that USAC has mitigated the possibility of rider/vehicle interactions is to avoid overly complex terrain where rides might take one of many lines on a technical selection. The course has been designed to minimize potential hazards, such as overly technical descents or areas with poor visibility, without compromising the competitive spirit of the race.
According to the tech guide for the 2024 event, the center line rule “stipulates that riders must stay on their side of the road, delineated by the centerline (or virtual centerline/center of road), throughout the race. Crossing the centerline, whether for overtaking or any other reason, is prohibited.”
I suppose it has to be this way and is probably not much of an issue when most or all of the roads look like this:
I think the GPS tracking is an interesting feature, it’s opt-in and not mandatory and I’m not clear if it’s free or what the cost will be. Also not clear how well it’s going to work or if there’s any prior history showing good effectiveness.
I’m hopeful I’ll never have to do a USAC gravel event.
