What is it?
Super League Triathlon's Championship
Series contains four races and sees athletes earn points towards the overall
leaderboard. At the end of each season,
the leaderboard decides the male and female Super
League Triathlon Championship Series
winners.
There are four events in the 2021
Championship Series: London (5 Sept), Munich (12 Sept), Jersey (19 Sept) Malibu (25 Sept).
Super
League is the only globally broadcast
series that answers the question: Who is the fastest triathlete in the world?
The series also offers a prize purse
of $1.25m (just under £904,000), ensuring the best talent on
the start line and competitive
racing.
What is the format?
Super League Triathlon has four formats: Enduro,
Triple Mix, Equalizer or Eliminator. The standard distances are 300m swim, 4km bike and 1.6km run.
The London leg will see athletes complete in the Triple Mix format. Athletes have a mass start and race swim-bike-run in stage one, before run-bike-swim in stage two. Stage three follows a pursuit style start - based on the athletes' times so far - and is done in a bike-swim-run format.
The winner is the first person to cross the line at the end of stage three. Athletes are eliminated at the end of a lap if they have fallen more than 90 seconds behind the leader.
In London points are awarded for the top 15 - with the winner earning 15 points and 15th place earning one point.
Is there anything else I need to know?
New for 2021 is the introduction of SLT teams - with athletes striding for team success alongside individual glory. There are five teams: Sharks (managed by Michelle Dillon), Rhinos (managed by Ronnie Schildknecht, Cheetahs (managed by Annie Emmerson), Eagles (managed by Tim Don) and Scorpions (managed by Chris McCormack).
The three-highest placed men and women from each team at every race of
this season's SLT will contribute the points earned as individuals to their
team's total. Points
earned via the swim, bike and run
leaderboards will also count.

As part of the build-up to this race Australia's Matt Hauser, who won gold in the mixed relay at the 2018 Commonwealth Games on the Gold Coast, spoke to BBC Radio 5 Live about the event.
Here's what he had to say...
"Super League Triathlon is all about the spectators and the entertainment. It is basically smashing ourselves for the entertainment of others. It should be electric out there!
"We enjoy smashing ourselves for others - it's alright. You get a natural high when you're pushing your body to the limits, and there is something different about the fact that you do all this training and you put it all out on the field of play and it either pays off or it doesn't. The fact that you've emptied the tank, there is something special about that. It is a self gratitude that you can hold your head high.
"To do it in the Super League format is quite cool. It is non-stop racing, fast and furious, and anything can happen."
