I created that RwGPS route based on tracing work done by another rider. I have no reason to doubt the work he did, but in the end, I was more comfortable doing my own trace.
When I saw the recent post from the ACP with new OpenRunner files, I did my own. Here’s what I did: I took a RwGPS upload of the OpenRunner outbound and inbound routes. I traced them with Google Maps base layer manually, not auto-trace. I added controls and food stops. I then stepped through them with "Review Cues." In that step I corrected a few errors, deleted a bunch of extraneous (to me) "Straight" cues, and changed turn designation at roundabouts from "straight" to "left" or "right" if those better matched what was happening at the roundabout.
I’m planning to use those instead of the one that you linked.
