James Alliston had quite the weekend at the 2026 USEA Young Event Horse West Coast Championships, sweeping both divisions aboard Wizmo Warrior OMR in the 4-year-olds and Viodor in the 5-year-olds.

But Viodor's victory was especially exciting, as his impressive score of 89.35 was the highest of any 5-year-old at this year's East and West Coast Championships, putting him first in line for the 2028 Holekamp/Turner Grant, which supports a trip to the FEI WBFSH Eventing World Breeding Championship for Young Horses at Le Lion d'Angers in France!

✨ In search of her next in barn lease ✨
Catina, 15.2 Holsteiner mare. Her current person is headed off to college and we are looking for another rider to take over the reins! Catina is the perfect teacher. She is best suited for someone who knows the basics but can still be learning, she gets excited to jump but is never unsafe. Catina seems to be happy doing very low levels of eventing and is the same at shows as she is at home. Lease would ideally be 4-5 days/week located at Alliston Equestrian in Castro Valley, CA.
Contact Katelyn Oelrich for details.
