Ohanian, who is married to tennis legend Serena Williams, has added London to the meeting in New York, which is in its third year and takes place a fortnight later.The London event will take place at the 10,500-capacity stadium of English rugby giants Saracens in Barnet.Athlos is owned entirely by Ohanian's venture capital firm Seven Seven Six, which has assets of $900 million (£670m) -- but athletes will receive equity in the league if the competition succeeds.The athletes, who include 2023 100m world champion Sha'Carri Richardson and 2024 Olympic 200m winner Gabby Thomas, will compete for a prize pot of $2.1m (£1.5m).Athletes can earn up to $65,000 in each individual event, while overall champions will receive an additional $25,000, meaning an athlete winning in both cities could pocket $155,000."I've long been very obsessed with this 'F1 for track and field' analogy," Ohanian told the BBC."We come to expect the fastest cars in the world to tour the greatest global cities, and for people to come out and watch and celebrate this excellence."I envision Athlos to be a version of that and, as we grow this league, I'd love to add more cities and make Athlos truly global."'Treated with respect'Unlike American track legend Michael Johnson's failed Grand Slam Track series, Ohanian is treading more cautiously.After adding its London event in 2026, Ohanian's ultimate aim is to create a worldwide, season-long league and says he has been in discussions with the sport's governing body and "great partners" World Athletics."I'm at a very fortunate place in my career in my life where I don't want to do anything small," said Ohanian."I want to do things that have big impacts, that are about legacy."Ultimately we want to build a league around athletics, which historically has not had commercial success. This is a big moment for us."Seven disciplines will be contested in both London and New York -- the 100m hurdles, 100m, 200m, 400m, 800m, mile, and long jump -- with an athlete's combined points determining the overall event winner.
