WATCH: Katalyst passes stalls test and is set to make her debut at Chepstow next week
The situation on the day was a huge surprise to trainer Chris Grassick, and as a result, in order to be able to make her debut in future, she had to undergo a stalls test to prove that she is capable and willing to go in with no trouble.
Katalyst headed to Windsor last week for her stalls test and thankfully, she passed with flying colours, which you can see in the video below, and now she's on track to head to Chepstow next Thursday (14th) for her racecourse debut.

Chris Grassick got in touch with us today to provide a full update on her recent progress and this is what he had to say:
"We did a piece of work with her this morning, where she galloped with an older three-year-old unraced filly. Katalyst was sat about a length and half behind the other filly, swishing her tail a little bit and maybe looking reluctant to go past the leading horse.
With that in mind, rather than running her at Windsor in the Cateogry B, C and D restricted race, we'll send her to Chepstow to run in a Category C and D restricted race, where she'll be running against her own gender, as opposed to facing male counterparts.
Chepstow should be a good track to help her learn a bit more, as she can come on and off the bridle with the undulations in the course. Hopefully, she'll learn a lot from the experience and become more versatile when it comes to differing conditions, as it likely won't suit her as much as Newbury or Windsor would for a first run."
The same five Coral Racing Club members who were chosen as her 'Owners for the Day' for her debut race will get the chance to head to Chepstow next week given that she didn't participate at Newbury last time round.
As we build up towards next week, be sure to join us on the day across the Coral Racing Club and X (Twitter) for all the live updates ahead of Katalyst's debut race.
