[3] As a yearling in August 2010 Slade Power was sent to the sales at Doncaster where he was "bought back"[4] for 5000 guineas by the trainer Ed Lynam, acting on behalf of the colt's breeders.

On June, Slade Power raced in England for the first time when he contested the Sandy Lane Stakes at Haydock Park Racecourse.

He tracked the leaders, moved into second place a furlong out, and took the lead in the closing stages, and won by a neck from Es Que Love, with Lethal Force a length away in third.

"[10] Slade Power did not race again until 20 October, when he was sent to England for the Group Two British Champions Sprint Stakes over six furlongs at Ascot Racecourse.

Slade Power sustained a fractured pelvis in the race and, according to Lynam, his life was saved by the treatment administered by the veterinary physician Simon Knapp.

A month later he started at odds of 10/1 for the Diamond Jubilee Stakes at Royal Ascot, but after a poor tart he finished seventh, almost six lengths behind the winner Lethal Force.

[13] Twelve days later, he ran in the Nunthorpe Stakes at York Racecourse but never recovered from a poor start and finished fifteenth of the seventeen runners behind the 40/1 outsider Jwala.

On his next appearance, Slade Power started at odds of 9/1 for the Group One Haydock Sprint Cup on 7 September with Lethal Force heading the betting at 5/2.

He tracked the leaders before taking the lead two furlongs from the finish and held on in the closing stages to win by a neck from Jack Dexter.

In the closing stages he hung left towards the centre of the course but won by one and a half lengths from the Aidan O'Brien-trained three-year-old Due Diligence.

He took the lead a furlong out and won by a length and a half from the 66/1 outsider Tropics, with Gregorian, who raced on the opposite side of the course, taking third ahead of Undrafted.

[18] After the race, Lynam named the Darley Classic in Australia as the horse's end of season objective, with the Haydock Sprint Cup as a possible interim target.

It's part of his nature... We always said this horse needed time and this was always going to be his year"[20] Slade Power made his final racecourse appearance in the Darley Classic but was unplaced, finishing eleventh of the thirteen runners behind Terravista.
