With the World Triathlon Series set to come to a close in Mexico this weekend, we’re going to take a look back at how one pair of brothers came to dominate the sport.
Since the series was introduced in 2009, there has been a Brownlee on the final podium in five of the seven years of competition.
With one round of competition to go this season, Jonathan Brownlee is currently in second place, and still in with a shot of taking the title back to Yorkshire.

After a 12th place finish at the Beijing 2008 Olympic Games, Alistair Brownlee took the triathlon world by storm in 2009, taking the overall title.
Brownlee took the win in five of the eight rounds of the series, including his home race in London, and the grand final on the Gold Coast, Australia.
With a total of 4,400 points, he got the better of future arch-rival Javier Gomez by 440 points.

As injuries took their toll on Alistair’s body he slipped down the rankings and finished up sixth overall.
The elder brother won the Madrid and Budapest events, but failed to rack up enough points during the rest of the season to figure on the final podium.
The year was significant for younger brother Jonathan’s first podium on the world level, taking second in London.

The year before the London 2012 Olympic Games and the Brownlees were almost unbeatable.
The brothers shared wins in five of the season’s seven events, with Alistair taking four and Jonathan taking one, to ensure they finished first and second in the overall standings.
Both Alistair and Jonathan were on the podium in four of the seven races, including a one-two in Madrid as they pushed home favourite Gomez into third – just as they did in the overall standings.

In the year dominated by the Olympic Games – in which the Brownlees took first and third – and in which Alistair faced a race against time to overcome an Achilles injury to be fit for London, it was Jonathan that took the season’s overall crown.
The younger sibling took three wins during the campaign, in San Diego, Madrid and Stockholm, while Alistair stood atop the podium in Kitzbuhel.
Jonathan also took second place in that Austrian race, as well as in Auckland, to ensure he was on the podium in five of the season’s eight races and took the title by 90 points from Gomez.

The Brownlees took six out of eight wins in the season, sharing three each, but it was Gomez’s consistency that earned him the overall title.
Alistair won in San Diego, Kitzbuhel and Stockholm as well as a second place in Hamburg, behind Jonathan, to finish the season in fourth.
And in addition to the Hamburg win, Jonathan triumphed in Yokohama and Madrid, as well as finishing third in Stockholm and second in London, to finish just 25 points behind the Spaniard, who made the podium in six of the eight races, including taking two victories.

In another year of injuries and periods out of competition for the brothers, Jonathan Brownlee took three podiums, in Auckland, Cape Town and Hamburg, as well as a win in Stockholm.
Alistair won in Hamburg and Edmonton, as well as finishing second behind his brother in Stockholm, but neither could beat the Spanish pairing of Gomez and Mola.
The 2013 champion took his second successive crown by 259 points from his compatriot, with Jonathan 100 points behind.

As the Brownlee brothers prepared for Rio 2016, ensuring their bodies were in peak condition for the biggest show on earth, the Spanish domination of the final rankings continued.
But while the final rankings show Gomez and Mola on top, when the Brownlees raced, they were still kings of the course.
Jonathan took wins in Auckland and Gold Coast, while Alistair stood atop the podium in Cape Town and London, as well as taking a second place in Yokohama.

With the world focussing on Rio, in August, the series took a back seat but Jonathan has not let that deter him from a push for the title.
Should he win in Mexico and Mola finish fourth or lower, the younger Brownlee will take his second World Triathlon Series title.
Alistair is currently sixth in the overall standings and cannot take the title, but having already taken his first ever aquathlon title in Cozumel earlier this week, he is showing no signs of post-Rio fatigue.
