This year, racehorse trainers and jockeys representing seven regions of Great Britain and Ireland will compete across six fixtures, beginning with a meeting at Doncaster on 6 August.
More than £2.0m (€2.4m/$2.4m) will be awarded across a total of 42 races, with teams earning points for their finishing positions in each race.
Prizes will also be handed out to the team and jockey that accumulates the most points across the 2022 Racing League.
“The innovative and unique concept of Racing League has always appealed to us at William Hill and, with the planned changes to the 2022 format, we’re really excited to be involved in Racing League once again,” William Hill’s director media, sponsorship and UK creative, Liam McKee, said.
“We’re looking forward to seeing who will win the race to the top and be crowned the 2022 Champions.”
Racing League chief executive Jeremy Wray added: “We took in a huge amount of feedback following the inaugural running of Racing League in 2021, and have been keen to add a number of innovations into this year’s competition.
“William Hill are, of course, well known and long-time supporters of racing in this country, and we are delighted to welcome them back to Racing League. We look forward to working together in promoting both their brand, as well as our competition to racing fans and their customer base alike.”
