Langley, British Columbia โ May 23, 2025 โ Tiffany Foster (CAN) is a household name at Thunderbird Show Park, but her new partner, Anton, is still getting acquainted with the place. The pair took their first win together in the $20,000 Tbird Challenge CSI 4* – 1.45m on Thursday of the Canadian Premier, proving theyโll be ones to watch as their partnership grows.
โThis is a new horse that we just got at the end of [the Florida winter circuit],โ Foster said of the 10-year-old Zangersheide stallion (Arko III x Quintero Z). โHeโs with my owners, the Cox family and 5 Roosters, who Iโve been working with for a few years now. They are amazing. They recognized that I had a few horses that retired and we were looking for another one.โ
Anton came into Fosterโs string in April and made his FEI debut with her that same month in Wellington, Florida, United States. She knew from the start that theyโd found something special.

โI call him a luxury purchase because I donโt often get to buy a 10-year-old horse,โ she explained, as a rider who typically brings along younger horses. โHe was developed by Max Kรผhner (AUT) in Europe. Heโs already jumped some big classes, so weโre just getting to know each other but Iโm really excited. Heโs got a great heart, heโs always with me, and I feel like every class we get a little bit better.โ
In Thursdayโs 1.45m competition, Foster was the first to produce a clear round, so she came back first for the jump-off. Having jumped only two international classes together prior, it was her first opportunity to test the speed gears on Anton.
โHeโs new so I donโt totally know his stride,โ she shared. โIn hindsight, I probably couldโve done eight [strides] from [fences] one to two. Same thing after the double, I couldโve done five [strides]. Once I get going with him, Iโll be able to drop those strides, but I made a decision after those two lines to opt for six in the last line. He ate up that line really easy. As Conor Swail (IRL) said, โYou did six, no bother.โ I never drop a stride so I was proud.โ

The pair came home on a clear effort in 37.64 seconds, and the next four riders had at least one rail down. The final rider, Samantha Buirs-Darvill (CAN), was the only other double-clear but finished nearly a second off the pace with Bryony Reidโs Maria 111. Buirs-Darvill also claimed third with Chic D Emma Z.
A Foster grew up competing at tbird and spends part of the year based in Langley. She routinely has horses that can tackle an expansive Fort Grand Prix arena. Anton is no exception, however that is not his primary role in her string.
โHeโs very careful, and I have a lot of horses that really suit big grass rings with bulky jumps, so I bought him more as not that horse,โ she went on. โBut I live in Langley so heโs going to have to jump at tbird and go to Spruce Meadows. Iโm going to give him a little time and let him get used to this kind of material. Iโll let him tell me what he wants to do over the next little bit.โ

The three-time Olympian has high hopes for Antonโs future.
โIโd love to aim for some of the big indoor shows in the fall with him,โ she said regarding what the rest of the year might look like. โA lofty goal would be to try to go to the World Cup Final with him next year. Heโs super easy to ride. Heโs agile and nimble and easy to navigate around a small ring, so I think thatโs a bit more his thing. Heโs also pretty awesome in the grass ring.โ
As the day wound down, Foster was very pleased to be in the winnerโs circle yet again in her hometown.
โI bought a house recently here so weโre laying roots down,โ she shared. โIโm really excited to have a farm [in Langley] and I love showing here, especially on a sunny day like this.โ
International athletes will compete Friday in the $62,500 Grand Prix Qualifier CSI 4* – 1.50m for a chance to enter into Sundayโs $116,050 Grand Prix CSI 4* – 1.55m.
