Dr. David Vos and the USEA’s Cross-Country Safety Subcommittee have developed a low cost, easily constructed testing system in order to test obstacles with frangible fence equipment to ensure that the fence will collapse when impacted under appropriate conditions.
The only materials needed for the test are:
“The whole point is to come up with an approach or means in which we can not only test future devices, but also current devices,” explained Vos. “In the field it is often not very obvious why [a frangible device] didn’t release. The point is to get to very strongly physics based solutions that are really easy to use in the field.”
Watch Dr. Vos demonstrating the test:

The Area III Championships kicked off the 2022 USEA Area Championship season June 24-26 at the Stable View Summer H.T. in Aiken, South Carolina. Offering 12 different championship divisions from Intermediate to Beginner Novice, the championships were highly contested as riders from all across Area III put in a gallant effort in hopes of being deemed division champion. The USEA caught up with many of the individual champions to look back on their performances in Aiken that helped them bring home the top prize.
The United States Eventing Association (USEA) is pleased to announce the athletes selected for the 2022 USEA Emerging Athlete 21 (EA21) Program. USEA Young Rider program members aged 21 and under are eligible for the program, which aims to creates a pipeline for potential U.S. team riders by identifying and developing young talent, improving horsemanship and riding skills, and training and improving skills and consistency.
The USEA American Eventing Championships (AEC) presented by Nutrena Feeds are just two months away. The AEC moves to the mountains this year, taking place at Rebecca Farm in Kalispell, Montana across a long Labor Day weekend.
