Hollie Doyle previews a busy weekend of racing action at York and Newbury, with her standout ride being Zeus Olympios in Saturday's Group One Lockinge Stakes at Newbury. The Karl Burke-trained colt finished third on his seasonal return in the Bet365 Mile and looks ready to step up to the highest level.

Doyle also highlights several promising mounts across both meetings. At York, Archie Watson's juvenile Niewiadoma steps up to Listed company after a debut win at Thirsk, while Call Margot represents Gemma Tutty in the Irish Thoroughbred Marketing Handicap. On the Newbury card, Juddmonte's Sintra seeks to build on an impressive handicap debut victory.

The Lockinge Stakes promises to be a fascinating contest with John and Thady Gosden's Damysus likely to provide stiff competition after winning the Earl of Sefton. However, Doyle believes Zeus Olympios has the class to make his mark at Group One level and could announce himself as a major player for the season ahead.
