I think the biggest issues were the misdirect at the beginning, and then the lateness of cancellation along with failing to get all the competitors on course stopped as soon as the cancellation happened.
There were other problems for sure, but I think those problems are not Tryon’s fault. Arguably the only issue for which Tryon may be wholly responsible is the misdirect at the start. The cancellation is on the FEI officials. The horses in distress is mostly a conditioning/rider awareness issue. I don’t think Tryon or America should be “ashamed” - the facilities were not as finished as they should have been for a competition of this caliber, but given the time frame they had to work with and various circumstances outside of their control (delays earlier this year because of mudslides and other regional issues), I think they’ve pulled most everything off pretty well. I was most worried about the XC portion of eventing and that went off very well.
I do think FEI needs to rework endurance and take a hard look at that, but I don’t think that’s the fault of Tryon or that we as American horse people need be ashamed of that.
