Forecast for warm day prompts watering on all three courses
Racegoers at Aintree on Saturday are promised glorious sunshine and temperatures in the high teens, prompting clerk of the course Andrew Tulloch to water all three courses on Friday evening.
Tulloch, who changed the going before racing on Friday to good on both the Mildmay and hurdles courses, and to good, good to soft in places on the Grand National course, confirmed: "The forecast is for a dry, warm day, similar to Friday but warmer, so I'll be watering all three courses.
"We'll look to maintain the ground as it is. I don't want it any drier underfoot than today."
The forecast warm weather has brought additional concerns for horse welfare, but the staff at Aintree are well drilled.
The track's veterinary advisor Chris Proudman said: "Warm weather is a really nice problem to have, because we want everyone to have a great time, and we are prepared.
"We're looking at temperatures of around 16 or 17 degrees by the time the Grand National is run and that means an increased risk of overheating.
"We have a dedicated wash-down facility adjacent to the pull-up area, where it is shaded, and we have a dedicated team at work under the supervision of vets.
"We have hi-tech misting fans, which were developed for the Atlanta Olympics and are widely used in eventing, and we also have buckets of water and sponges."
He added: "We'll also be advised in the morning through the horse welfare data kept by the BHA of any runners known to be at particular risk, so we can keep a close eye on them."
