The 14th stop of the Longines Global Champions Tour (LGCT) takes place this weekend with title race hotting up.
Leader Pieter Devos can extend his 17-point advantage in the absence of second-ranked Daniel Deusser of Germany, but he will face stiff competition from third-placed Ben Maher, who will have the support from his home crowd.
Olympic gold medalist Maher is the reigning LGCT champion, but he in turn will face renewed rivalry with fellow Briton Scott Brash.
The pair have played out some great duels in London in previous years, with Brash looking for a hat-trick of wins in England’s capital.
In fact, there have been four British champions in the last five editions of the London event.
The star-studded line-up in London will include three members of the famous Whitaker family — Michael, Robert and William.
Also competing are the likes of former world No.1 Harrie Smolders, Chantilly winner Darragh Kenny and Australian star Edwina Tops-Alexander.
