Warwick racecourse staged a successful trial after the realignment of its sprint course following remedial work.
Jockeys had reported a loss of confidence in some areas of the track after Artful Lady suffered a fatal fall in May.
Two fixtures (July 4, August 25) will now take place on the sprint track while others have already been moved to Nottingham and Carlisle.
Jockey Fergus Sweeney was present in his role as the Professional Jockeys Association safety officer and said: "We were perfectly happy, they have done a good job and it was really nice ground.
"The configuration of the rails was spot on and this was a real test, we all came together on the turn and were going as quick as we could have done at the sharpest point.
"We got round it fine, it rode really well. It was lovely ground and there will be no problems for the next fixture - it gets the thumbs up from the lads."
All races at the two meetings will be sprints and will take place on ground no faster than good, achieved through watering if required.
